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.
