Halide Perovskites have gained much attention in the past decade owing to their impressive optical and electrical properties like direct tunable bandgaps, strong light absorption, high photoluminescence quantum yield, and defect resistance shown by them. These materials find application in numerous fields including photovoltaics, optoelectronics, catalysis, and lasing applications. Multidimensional hybrid perovskites have been extensively researched as these structures lead to superior results. They combine the properties of three-dimensional variant along with the stability of the two-dimensional perovskite. This chapter focuses on the unique properties of metal halide perovskites including the crystal structure, optical, electronic, and electrical properties. The different techniques followed for the synthesis of metal-halide nanostructures and 2D/3D hybrids are also included focusing on the changes in physical properties and the structure of these materials.

Biomaterials have occupied a prominent place in regenerative procedures to restore human health. Moreover, there is a greater need in understanding, analyzing and establishing their toxicity profile. These, when made into nano-sized constructions called nanostructured biomaterials, their regenerative potential is enhanced, which could influence their toxicity nature. This chapter intends to give comprehensive information on their nanotoxicology pathways at the cellular level, their entry pathways into the human body, and their potential consequences on human health. It clearly explains the cytocompatibility and biocompatibility of various nanostructured biomaterials for potential human health applications like drug delivery and tissue engineering. A detailed overview of various in vitro and in vivo evaluation methods of biocompatibility of nanomaterials are outlined in this chapter that researchers should address as they move forward in developing new systems for the field of regeneration.
