Perovskite (Calcium titanium oxide), which was discovered in 1839 by
Perovski, a Russian mineralogist, has some favorable photophysical characteristics that
enable perovskite and its nanocrystals to be used in the field of biomedical research.
Presently, perovskites are being explored for various medical applications, including
X-ray detection and imaging, cancer treatment, orthopedic implants and as
antimicrobial agents. Advancements in nanocrystal research allowed the exploration of
perovskites for their antibacterial, antifungal and antiviral activity against Severe Acute
Respiratory Syndrome Corona Virus 2 (SARS-CoV-2). The antibacterial activity of
several perovskite nanoparticles was explored, and to mention a few, Cesium lead
bromide and zinc oxide perovskite nanoparticles showed activity against Escherichia
coli, while Lanthanum potassium ferrate and silver-based perovskites against
Staphylococcus aureus and Pseudomonas aeruginosa. This chapter will review the
potential research studies that explored the anti-microbial activity of perovskites and
their nanoparticles against bacteria, viruses, fungi and other microorganisms and
provide insight into the mechanisms by which these particles exert antimicrobial
action. Further, this chapter will discuss the potential biomedical applications of the
antimicrobial activity of perovskites.
