Abstract

Perovskite materials are well-known for their remarkable thermal, optoelectronic, and magnetic capabilities. This chapter examines current advances in the study of biological applications involving perovskites. This chapter looks at how organic-inorganic hybrid perovskites can be used for X-ray detection and imaging. This can be achieved by switching to Cs+ -cations or MA+/Cs+ alloyed motifs, which not only widen the band gaps but also enhance the structural stability of perovskite materials. The future research direction should focus on fabricating large-area and thick 2D perovskite absorbers on thin-film transistor arrays through compatible printing (polycrystalline) and self-assembled (monocrystalline) methods to achieve X-ray detectors and imagers with high sensitivities and responsivities. The detailed material phases of La0.7Sr0.3Mn0.98Ti0.02O3 perovskite nanoparticles have not been unambiguously elucidated due to inaccurate relative compositions of metal cations. Therefore, insightful structural analysis of the material is needed for confirmation of the magnetically thermally active phase. In the case of perovskite La2NiMnO6 nanoparticles, their ability to desorb BSA protein molecules has not been studied, which is required to fully comprehend the binding/detachment dynamics of enzyme reactions. Finally, the future research direction of CaTiO3 -based composites is to further understand their structure-property relationships under more complicated chemical environments with variations in temperature, pH, and pressure, given their promising biocompatibility and cytotoxicity.
