Kevlar-based protective gear is often considerably lighter and thinner than equivalent gear made of more traditional materials. [26] Kevlar is a very popular material for racing canoes. It is used for motorcycle safety clothing, especially in the areas featuring padding such as the shoulders and elbows.
SEM image of pollen grains. Sporopollenin is a biological polymer found as a major component of the tough outer (exine) walls of plant spores and pollen grains. It is chemically very stable (one of the most inert among biopolymers) [1] and is usually well preserved in soils and sediments.
It is not given that bio-based materials always perform better than fossil-based materials. [15] [16] Their environmental performance depends on a series of factors, related to the sourced material and to the amount and typology of manufacturing processes the raw natural material need to undergo to become a bio-product.

A hip implant is an example of an application of biomaterials. 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.
The uniformity of both specific types of molecules (the biomolecules) and of certain metabolic pathways are invariant features among the wide diversity of life forms; thus these biomolecules and metabolic pathways are referred to as "biochemical universals" [4] or "theory of material unity of the living beings", a unifying concept in biology ...
Biocompatibility (or tissue compatibility) describes the ability of a material to perform with an appropriate host response when applied as intended. A biocompatible material may not be completely "inert"; in fact, the appropriateness of the host response is decisive. [15]
What one nurse learned about humanity amidst the Ebola epidemic
Alternatively, the bioceramic materials can be doped with β-emitting materials and implanted into the cancerous area. [2] Other trends include engineering bioceramics for specific tasks. Ongoing research involves the chemistry, composition, and micro- and nanostructures of the materials to improve their biocompatibility. [16] [17] [18]
