ASSIGNMENT - 1NAME S/LT NAEEM SARWAR PNP.NO 8817CLASS IV-MESEC B1-BIOMATERIALS:DEFINATION:Biomaterials are those which can be explained as a substance introduced into the body tissue as its part of medical devices or used in place of an organ.COMPOSITION: Biomaterials consist of • Metals • Ceramics • Semiconductors • Plastics • Composites INTRODUCTION: Biomaterials are derived from nature or in the laboratory using various chemical approaches using metallic components, e.g. composites, polymers and ceramic materials. These materials are usually used for medical applications and consist of part or all of a living structure or a biomedical device that performs a natural function. These materials are most likely used for human heart valves and veins or may be bioactive with interactive functionality such as hip prosthetics. Biomaterials are also used daily in drug delivery and even dental surgical applications. Nowadays, biomaterials scientists are paying more and more attention to the progress of inorganic crystallization within largely organic compounds as expected. These processes typically occur at a certain temperature and pressure. Interestingly, animate organisms are through which these crystalline forms of minerals are able to consistently produce intricate and complex structures. Considering that the processes of living organisms are capable of making the growth of crystalline minerals, such as silica, flexible, could lead to meaningless scientific mixing techniques for nanoscale composite materials. The word biomaterial is used for materials that can be used in clinical and biomedical applications. These biomaterials are biocompatible in nature. Currently many types...... middle of paper ......concerning linear and nonlinear optical fields, the need for temperature, resistivity spin resonance spectra and magnetic susceptibility dimensions. Numerous fascinating and thought-provoking results have been industrialized that guide our perspective in understanding quantum excavation, quantum stage change, surface effect quantum size effect confinement, and nonlinear susceptibility enhancements. NATURAL NANOMATERIALS: The good structure of viruses, wax crystals cover a lotus or leaves and red spider silk, the (spatula) on the bottom of gecko legs, butterfly wing scales, natural colloids, milk blood, materials cornei “hair, beaks, feathers, horn skin” and even our bone matrix are all natural organic nanomaterials. Natural inorganic nanoparticles come from natural wear or volcanic action but also from fire. The results of burning mineral cement and pigments.
