Biomaterials

Image
A biomaterial is any 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. As a science, biomaterials are about fifty years old. The study of biomaterials is called biomaterials science or biomaterials engineering. It has experienced steady and strong growth over its history, with many companies investing large amounts of money into the development of new products. Biomaterials science encompasses elements of medicine, biology, chemistry, tissue engineering and materials science. Note that a biomaterial is different from a biological material, such as bone, that is produced by a biological system. Additionally, care should be exercised in defining a biomaterial as biocompatible, since it is application-specific. A biomaterial that is biocompatible or suitable for one application may not be biocompatible in another. Biomaterial...

Nanomedicine: The Future of Medicine

Image
                                 Nanomedicine  is medicinal use of nanomaterials or nanoparticles, wherein they are used as a transport for drugs to deliver them to the innermost target areas that wouldn’t have gone otherwise. Nanoparticles utilized as sedatives are about 1/20 th  to 1/100 th  nanometre; however this is conditional depending on the nature of the nanoparticle used. Nanomaterials can be designed as per the required conditions by adding functionalities by interfacing them with various bio-molecules and are used both,  in vivo  and  in vitro  research applications. This assimilation of nanomaterials with bio-molecules had been crucial in developing nano-diagnostic devices, analytical tools, contrasting agents, drug delivery vehicles and also are being used for physical therapy. Nanomedicine has reduced the overall drug consumption and their side-eff...
