Biomaterials Consulting & Design & Development

Biomaterials are natural or man-made materials, that comprises whole or part of a living structure or biomedical device which performs, augments, or replaces a natural function. Biomaterials are used in medical applications dental applications, surgery, and drug delivery (a construct with impregnated pharmaceutical products can be placed into the body, which permits the prolonged release of a drug over an extended period of time). Biomaterials may have a benign function, such as being used for a heart valve, or may be bioactive with a more interactive functionality such as hydroxy-apatite coated hip implants. Biomaterials may be man-made materials constructed of metals, ceramics, or be autografts, allografts or xenografts used as transplant materials.

Biomaterials are widely used in:

  • Bone cement

  • Bone plates

  • Joint replacements

  • Artificial ligaments & tendons

  • Blood vessel prostheses

  • Heart valves

  • Skin repair devices

  • Dental implants

  • Cochlear replacements

  • Contact lenses

  • Breast implants

  • Other body implants


Biomaterials compatibility (biocompatibility) with the body must be resolved and assured before a product can be placed on the market and used in a clinical setting. Because of this, biomaterials are usually subjected to the same requirements of those undergone by new drug therapies. Biocompatibility is related to the behavior of biomaterials in various environments under various chemical and physical conditions. Biocompatibility may refer to specific properties of a material without specifying where or how the material is to be used. For example, a material may elicit little or no immune response in a given organism, and may or may not be able to integrate with a particular cell type or tissue). Modern medical devices and prostheses are often made from several different materials, therefore it may not always be possible to talk about the biocompatibility of a specific material.


Furthemore, a material should not be toxic unless specifically engineered to be so such as smart drug delivery systems that target cancer cells to destroy them. Understanding of the anatomy and physiology of the action site is essential for a biomaterial to be effective. An additional factor is the dependence on specific anatomical sites of implantation. It is thus important, during the biomaterials design, to ensure that the implement will fit complementarily and have a beneficial effect with the specific anatomical area of action.



We offer biomaterials design, development, analysis and testing services supporting development and market approval for medical devices and drug device combinations, consulting, expert witness and litigation services.



Our biomaterials design and development engineers and scientists have expertise in design and manufacturing biomaterials for large IVD manufacturers with proven results in diagnostic kits. Biological tissues are intrinsically organized at multiple scales, they perform multiple structural and physiological functions. Biomaterials are used to substitute the biological tissues and they should therefore be designed in the same way. Our subject experts have the knowledge and know-how in the many scientific facets of these complex materials and applications including biology, physiology, mechanics, numerical simulation, physical chemistry...etc. Their close relationships and experience with clinical research and an easy access to many characterization and visualization techniques are our valuable assets.


One major design area, “Biointerfaces” are critical to the control of the cell response to biomaterials. Biochemical and physico-chemical properties of biointerfaces regulate cell adhesion to biomaterials and uptake of nanoparticles. Polymer brushes, polymer chains attached at one end only to an underlying substrate are coatings to control such biointerfaces. These coatings allow tailoring the physico-chemical properties of biointerfaces via the control of their thickness, chain density and the chemistry of their constitutive repeat units and can be applied to metals, ceramics and polymers. In other words, they allow the tuning of bioactive properties of a wide range of materials, irrespective of their bulk and surface chemistry. Our biomaterial engineers have studied protein adhesion and interaction to polymer brushes, they have investigated the biofunctional properties of the biomolecules coupled to polymer brushes. Their in-depth studies have been useful in the design of coatings for implants, in vitro cell culture systems and for the design of gene delivery vectors.


Controlled geometry is an inherent feature of tissues and organs in vivo. The geometrical structure of cells and tissues at multiple length scales is essential to their role and function, and a hallmark of diseases such as cancer as well. In vitro, where cells are culture on experimental plastic dishes, this control of geometry is typically lost. Reconstructing and controlling some of the geometrical features of biological systems in vitro is important in the development of tissue engineering scaffolds and the design of cell based assays. It will allow a better control of cell phenotype, higher degree structure and function, which are essential for tissue repair. This will allow more accurate quantification of cell and organoid behaviour in vitro and determination of the efficacy of drugs and treatments. Our biomaterials engineers have developed the use of patterning tools at different length scales. These patterning techniques have to be fully compatible with the chemistry of the biomaterials on which these platforms are based, as well as the relevant cell culture conditions.


There are many more design and development issues that our biomaterials engineers have worked on throughout their careers. If you would like specific information regarding a particular product please contact us.



To design, develop and manufacture safe and effective biomaterial products, while meeting the regulatory requirements of marketing authorization, robust laboratory testing is required in order to understand aspects related to product safety, such as the tendency of biomaterial products for releasing leachable substances, or performance criteria, such as mechanical properties. We have access to a wide range of analytical capabilities in order to understand the identity, purity, and biosafety of a growing number of biomaterials utilized in medical products through physical, chemical, mechanical, and microbiological testing methodologies. As part of our work we help manufacturers assess the safety of finished devices with supporting toxicological consulting. We provide analytical services to support product development and quality control of raw materials and finished products. We have experience with many types of biomaterials such as liquids, gels, polymers, metals, ceramics, hydroxyapatite, composites, as well as biologically sourced materials such as collagen, chitosan, peptide matrices, and alginates. Some major tests we can conduct are:


  • Chemical characterization and elemental analysis of biomaterials to achieve a comprehensive understanding of the product for regulatory submission and for the identification or quantification of contaminants or degradation products. We have access to labs that are equipped with a wide range of techniques to determine chemical composition, such as infrared spectroscopy (FTIR, ATR-FTIR) analysis, nuclear magnetic resonance (NMR), size exclusion chromatography (SEC) and inductively-coupled plasma spectroscopy (ICP) to identify and quantify composition and trace elements. Elemental information about the biomaterial surface is obtained by SEM / EDX, and for bulk materials by ICP. These techniques can also highlight the presence of potentially toxic metals such as lead, mercury and arsenic inside and on biomaterials.


  • Impurity characterization using laboratory-scale isolation and a range of chromatography or mass spectrometry methods such as MALDI-MS, LC-MSMS, HPLC, SDS-PAGE, IR, NMR and fluorescence…etc.


  • Biomaterial polymer analysis to characterize the bulk polymer material as well as determine the additive species such as plasticizers, colorants, anti-oxidants and fillers, impurities such as unreacted monomers and oligomers.


  • Determination of biological species of interest such as DNA, Glycoaminoglycans, total protein content…etc.


  • Analysis of actives incorporated into biomaterials. We conduct analytical studies to define the controlled release of these active molecules such as antibiotics, antimicrobials, synthetic polymers and inorganic species from the biomaterials.


  • We conduct studies for the identification and quantification of extractable and leachable substances that arise from biomaterials.


  • GCP and GLP bioanalytical services supporting all phases of drug development and non-GLP rapid discovery phase bioanalysis


  • Elemental analysis and trace metals testing to support pharmaceutical development and GMP manufacturing


  • GMP stability studies and ICH storage


  • Physical and morphological testing and characterization of biomaterials such as pore size, pore geometry and pore size distribution, interconnectivity, and porosity. Techniques such as light microscopy, scanning electron microscopy (SEM), surface areas determination by BET are used to characterize such properties. X-Ray diffraction (XRD) techniques are used to study the degree of crystallinity and phase types in materials. 


  • Mechanical and thermal testing and characterization of biomaterials including tensile tests, stress-strain and failure flex fatigue testing over time, characterization of viscoelastic (dynamic mechanical) properties and studies to monitor the decay of properties during degradation.


  • Medical device materials failure analysis, determination of root cause
