Abstract
Within the context of the medical field, this chapter explores the possible
uses of perovskite materials, piezoelectric nanogenerators (PENGs), piezoelectric
biomaterials, and metal halide nanocrystals. As a result of their one-of-a-kind qualities,
perovskite materials have recently gained attention as possible candidates for use in
medical diagnostics, treatments, and imaging methods. However, before their broad
application in the biomedical sector, difficulties relating to biocompatibility, stability,
biodegradability, integration with current technologies, and scalability need to be
overcome. PENGs provide self-powered health monitoring devices and may be utilized
as a power source for microdevices and bio-implants, bypassing the limits of current
power sources. PENGs are also capable of being employed as a power source for other
applications. Theranostic methods, tissue regeneration, and drug delivery systems are
all potential uses for piezoelectric biomaterials like BT, ZnO, and nanoparticles based
on BFO. Nanocrystals made of metal halides, such as CsPbX3, have extraordinary
light-harvesting capabilities that make them ideal for use in photonic-based biomedical
applications. These applications include multi-photon excitation for cellular imaging
and photoactivated treatment. Additional study is required to fully investigate the
capabilities of these materials and find solutions to the obstacles that stand in the way
of their clinical use. Some of these obstacles include biocompatibility, biodegradability,
and tissue accumulation.
