Among several gems unraveled in material science, hybrid nanomaterials are one of the most exciting fields of research. Owing to its multidisciplinary nature, advances in technology and science in this field have attracted a lot of attention. Organic and inorganic components present in such materials give rise to diverse multifunctional attributes with unique physiochemical properties. Hybrid nanomaterials have been modified for several applications like batteries, supercapacitors, sensors, catalysis, etc. There is an ever-growing demand for functionalized nanomaterials in the biomedical industry. Synergistic materials have the potential to replace pristine materials for diagnostic and clinical purposes. In this regard, specific organic-inorganic counterparts not only have emerged as a versatile system but are being implemented for biological platforms such as drug delivery, photothermal therapy, vaccines, etc. This chapter focuses on the development of hybrid nanomaterials, their properties, and their significance in biomedical engineering. It also highlights the architecture of hybridization and future prospects.
