The human bodyHuman body experiences many wearsWear and tearsTear with aging, and sometimes human organsHuman organs and tissuesTissue fail to function properly because of certain genetic defectsGenetic defects, diseasesDisease, traumaTraumas, injuriesInjuries, disordersDisorders, and eventually with age. The day-to-day medication by drugsDrug can handle some of these conditions, but sometimes the administration of medicinesMedicine is not sufficient for complete repairRepair/recoveryRecovery of these disordersDisorders. In that case, biomaterialsBiomaterials that have the features of facile fabrication, mechanical stabilityMechanical stability, biocompatibilityBiocompatibility, and inertnessInertness are used to maintain the regular functioning of the body. BiomaterialsBiomaterials are chemicalChemical entities, which are designed and developed to interact effectively with biological systemsBiological system, thus providing a platform for the improvement of bioBio-artificial implantations. These materialsMaterial are either synthesized using the nanostructured technology, chemicalChemical and physicalPhysical approaches or engineered with the cellsCell and tissuesTissue for their biocompatibleBiocompatible applicationsApplications for various diagnosticDiagnostic and therapeuticTherapeutic purposes. The advancement in biomaterialsBiomaterials is a continually rising research field signifying the introduction of definite materialsMaterial for supplementing or substituting humanHuman tissuesTissue. BiomaterialsBiomaterials are being used throughout the body and have a great impact on the treatment of different types of diseasesDisease and wounds. Owing to their eco-friendlyEco-friendly nature and biodegradabilityBiodegradability, they are widely used for biological applicationsBiological applications. The chapter surveys and discusses some of the biomaterialsBiomaterials that have been used or are under consideration for use in biomedical applicationsBiomedical application.
