The Workflow & Process For Biomaterials In Life Sciences


Biomaterials are used across a wide array of applications in life sciences. In most cases these materials are highly engineered and fit for purpose to the particular application or even patient. Below is a general overview of the typical workflow and processes involved in designing, developing, manufacturing, and distributing biomaterial solutions in life sciences. 


Conceptualization, Design & Development

Conceptualization, design, and development of biomaterials are multidisciplinary activities that bring together experts in materials science, biology, and engineering. These experts collaborate on everything from material selection, prototyping, feasibility studies, risk assessments, and regulatory considerations. This collaborative work sets the stage for successfully commercializing novel biomaterials innovations. 


Material Selection

Material selection is critical in developing biomaterials and must occur early in the conceptualization phase. Material selection involves evaluating factors like biocompatibility, mechanical properties, and alignment with the specific functionality requirements of the intended application. In addition to optimal performance, a material must be economically viable and manufacturable and adhere to the intended application's specific quality and regulatory requirements.  


Concept Generation

During concept generation, teams work to translate their ideas into biomaterial concepts. Background research and brainstorming sessions will help define the concept and discover intellectual property. The research will include literature reviews and interviews with various stakeholders, such as doctors and clinicians, who can help define the clinical problem. Concepts will then be assessed for viability so that further work can be done to develop the most promising concepts. 


Concept Development & Feasibility

During concept development, work focuses on refining the biomaterial concept and assessing its feasibility. Feasibility studies are conducted to determine the practicality and viability of the proposed biomaterial solution. These studies encompass a range of assessments, from theoretical analyses to preliminary lab-based experiments. They provide crucial insights into the potential performance and functionality of the biomaterial within the specific context of the intended application. The results of the feasibility work are reviewed to guide next steps. 


Development & Validation

Once a technically viable concept is designed, the next steps of development can be pursued to translate the biomaterial design into a validated product that can be manufactured. At this stage, a more rigorous development plan is needed to outline tasks and milestones and allocate resources to the work. Design inputs will be generated based on user needs and risk management activities, and these inputs will be used to guide the work.  


Risk Assessments & Regulatory Considerations

Risk assessments are conducted throughout the design phases to identify and mitigate potential challenges or shortcomings in the design. This proactive approach ensures that potential issues are addressed early in development. Regulatory considerations specific to the intended application are also considered early on. A clear understanding of the existing standards of care and other guidelines is integral to ensuring that the biomaterial solution will successfully integrate into the broader healthcare system.

Material Synthesis & Formulation

The synthesis and formulation of biomaterials are foundational steps that shape the potential and performance of these specialized materials. Biomaterials are precisely engineered from a wide range of raw material components to create the precise molecular structures required for their intended applications. Synthesis and formulation methodologies are specific to each biomaterial application and are ultimately critical in achieving the desired mechanical and chemical characteristics.  



Specialized synthesis methods create biomaterials from raw components or precursor materials. For instance, in the case of polymers, controlled polymerization techniques are utilized to engineer the desired molecular structure precisely. For ceramics, sophisticated processing methods are employed to craft intricate compositions. With metals, advanced alloying techniques produce biomaterials with tailored mechanical and chemical characteristics. These synthesis processes are controlled to ensure that the resulting biomaterials meet the exacting standards of their particular application. 



Once synthesized, biomaterials typically undergo a series of processing steps to achieve the desired form. These steps may involve intricate techniques such as controlled casting, precision extrusion, or 3D printing. Processing methods are selected based on the intended application's specific material properties and functionality requirements. 


Sustainability Considerations

Sustainability is an increasingly important factor in the design and commercialization of biomaterials. Researchers and manufacturers are advancing eco-friendly synthesis methods and utilizing recyclable or biodegradable precursor materials. These efforts align with the broader overall trend toward sustainable practices within the life sciences industry.


Functionalization and Modification

Functionalization and modification processes are essential components of biomaterial development, allowing for the customization of biomaterial properties for specific applications. These steps enhance the biomaterial's interaction with biological systems and optimize its performance.


Surface Modifications

Surface characteristics are crucial in determining how biomaterials interact with biological entities. Surface modifications involve altering the outermost layer of the biomaterial to achieve specific functionalities. These modifications can include techniques like tailored coatings, specific grafting methodologies, and integrating unique functional groups. For example, coating a biomaterial with a bioactive compound can enhance cellular adhesion, promote tissue integration, or facilitate controlled drug release. These modifications are developed to ensure that the biomaterial harmonizes with the biological environment it encounters while delivering its intended benefit. 



Biofunctionalization involves the incorporation of bioactive molecules into biomaterials. These molecules can include specialized growth factors, adhesion peptides, or other biologically active compounds. By integrating these bioactive elements, the biomaterial can induce specific cellular responses. For instance, a biofunctionalized scaffold in tissue engineering may promote cell adhesion and proliferation, guiding the formation of organized tissue structures. 



Rigorous testing and validation procedures are required to ensure that biomaterials are safe and effective. These procedures evaluate the biomaterial's performance, biocompatibility, and compliance with regulatory requirements.


Biocompatibility Testing

Biocompatibility is a cornerstone of biomaterial design. These tests evaluate the biomaterial's ability to coexist within the biological milieu without eliciting adverse reactions. It involves in vitro and in vivo assessments, examining cytotoxicity, immunogenicity, and tissue compatibility. These tests are standardized for the life sciences industry to ensure the biomaterial integrates seamlessly with biological systems.


Mechanical and Chemical Testing

Biomaterials' mechanical and chemical properties are also tested to ensure safety and reliability. Mechanical test methods evaluate parameters such as tensile strength, elasticity, and fatigue resistance. These assessments ensure that the biomaterial possesses the requisite mechanical integrity to withstand the conditions of the intended application. Chemical test methods assess degradation profiles, chemical stability, and potential leachables or extractables. These tests ensure that the biomaterial remains stable and reliable throughout its use. 



Manufacturing, Distribution, and Surveillance

The transition of a biomaterial device into commercial production, distribution into the market, and post-market activities are pivotal phases in the commercialization process. These commercialization steps involve meticulous planning, optimization, and quality assurance.  


Manufacturing Scale-Up

Manufacturing scale-up is a critical step in the commercialization process for biomaterials. This process requires the selection, specification, and validation of equipment. This process can take significant time and resources. The result is a reliable and repeatable manufacturing process supporting the commercialized product from initial launch to scaled distribution. 


Packaging and Sterilization

Specialized packaging is necessary to preserve the integrity and sterility of biomaterials during storage, transit, and before use. The packaging must be tailored to the specific requirements of the biomaterial, considering factors such as material compatibility, protection from environmental factors, and ease of handling for end-users. Sterilization procedures are required to eliminate potential contaminants and maintain the biomaterial's sterility. Typical sterilization techniques are gamma irradiation, autoclaving, or ethylene oxide sterilization, which are chosen based on their compatibility with the biomaterial.


Quality Control 

Quality control protocols are implemented in preparation for and during commercial production of biomaterials. These protocols ensure that the biomaterials conform to the precise specifications required for each specific application. Quality control protocols include batch testing to verify material composition, mechanical properties, surface characteristics, dimensional analysis, and compositional verification. Deviations from the defined quality standards must be identified and addressed promptly. 


Supply Chain Management

Close collaboration with raw materials suppliers is an important commercial activity to ensure a seamless production pipeline and reliable and consistent product supply. Procurement teams aim to mitigate potential risks associated with supply chains, including quality control issues and interruptions in raw material supply. Biomaterials may also have specialized handling and storage requirements that must be followed. 



Biomaterials designed for the life sciences market find diverse applications across clinical settings. These applications include advanced surgical interventions, tissue engineering procedures, drug delivery systems, and diagnostic techniques. The distribution of a biomaterial involves careful planning and coordination with healthcare professionals to ensure that the biomaterial is utilized effectively and safely in the clinical context. Ensuring proper use often involves specialized training for healthcare practitioners and detailed procedural guidelines to guarantee optimal outcomes.


Post-Market Surveillance

After biomaterials are distributed into healthcare settings, their performance and safety must continue to be monitored. Post-market surveillance involves systematic data collection, analysis, and reporting of adverse events or unexpected outcomes associated with using the biomaterial.
