Fluorescence behaviour of dyes in different microenvironments

Abstract

The study and application of extremely small objects, which are undetectable to the naked eye, and utilization of these nanomaterials in other branches of science, are known as nanoscience and nanotechnology. These nanomaterials exhibit unique physical and chemical properties due to their ultra-small size and large surface area. Considering these unique features, NPs can be used in a variety of applications like sensing, catalysis, bioimaging, light-emitting diodes (LEDs), drug delivery etc. NPs have attracted a lot of attention recently, and they're becoming an essential material in the development of new nanodevices that can be employed in a variety of physical, biological, medicinal, and pharmacological applications. Nanoscience has already seen significant advancements and discoveries. Many questions have been answered and important discoveries have been made. Synthetic procedures for precisely modifying the shape, size, and characteristics of colloidal nanoparticles (NPs) have been well explored, and continuous advancements and improvements have been made to date. Many NPs superstructures have been constructed with new attributes and applications, emulating the behaviour of well-organised natural machines (e.g. proteins, enzymes, biopolymers). This concept has influenced various major domains, including energy and biology.
