A biomaterial is a substance that has been engineered to interact with biological systems for a medical purpose – either a therapeutic (treat, augment, repair, or replace a tissue function of the body) or a diagnostic one.
In this regard, the application of bio-based materials has been already tested on several market segments, ranging from the production of chemicals, to packaging and textiles, till the fabrication of full construction components. [9] Bio-based materials can differ depending on the origin of the biomass they're mostly constituted. [10]
At first, the study of biometals was referred to as bioinorganic chemistry. Each branch of bioinorganic chemistry studied separate, particular sub-fields of the subject. However, this led to an isolated view of each particular aspect in a biological system. This view was revised into a holistic approach of biometals in metallomics. [2]
According to Griffith's theory of fracture in tension, the largest flaw or crack will contribute the most to the failure of a material. Strength also depends on the volume of a specimen since flaw size is limited to the size of the specimen's cross section. Therefore, the smaller the specimen (e.g., fibers), the higher the fracture strength.
Biodegradable polymers are a special class of polymer that breaks down after its intended purpose by bacterial decomposition process to result in natural byproducts such as gases (CO 2, N 2), water, biomass, and inorganic salts.
Biotic material or biological derived material is any material that originates from living organisms.Most such materials contain carbon and are capable of decay.. The earliest form of life on Earth arose at least 3.5 billion years ago.
Towards improving the performance of transplanted porous bioceramics, numerous processing techniques are available for the control of porosity, pore size distribution and pore alignment. For crystalline materials, grain size and crystalline defects provide further pathways to enhance biodegradation and osseointegration, which are key for ...
Biomimetic materials in tissue engineering are materials that have been designed such that they elicit specified cellular responses mediated by interactions with scaffold-tethered peptides from extracellular matrix (ECM) proteins; essentially, the incorporation of cell-binding peptides into biomaterials via chemical or physical modification.
