Nanotechnology is a swiftly expanding domain with significant applications across various disciplines. Platinum nanoparticles (PtNPs) represent a focal point in scientific investigations, drawing considerable research attention due to their potential applicability in diverse fields. Their inherent non-toxicity and remarkable stability confer distinctive plasmonic properties, rendering them particularly valuable in the realm of bioengineering. This review aims to comprehensively assess the ongoing global research landscape pertaining to the synthesis, mimicry, and utilization of PtNPs. The review covers the biosynthesis, as well as chemical and physical synthesis of PtNPs, incorporating both in-vivo and in-vitro experimental analyses. After their synthesis, a range of nanometrological characterization techniques is explored as analytical tools to facilitate the measurement of physical and chemical properties of nanoparticles. Additionally, the review delves into recent advancements in the functionalization of PtNPs for biomedical applications, encompassing areas such as nanomedicine, combination therapy, cancer treatment, and antibacterial properties.
