Have you heard about Biomimetics? This is a well researched area of materials science dealing with the science of copying or improving upon things found in nature. A very common example of Biomimetics is synthetic versus natural rubber.
Another advanced example of Biomimetics is development of materials which can be used within the human body and these are inert materials which can be incorporated in natural tissues resulting in any adverse reaction.
Now a number of developments in the field of biomimetics are utilizing nanotechnology for producing molecular level changes to materials for mimicking naturally found materials. This field is being used for encouraging bone regeneration and interaction with human implants and orthopaedic implants and it has been found out that better results can be achieved with smaller sized particles. Using nanotechnology researchers have already been able to successfully mimic molecular transport systems within the body for building nanosized machines which can move particles.
