Emerging frontiers in spiropyran-driven photoresponsive drug delivery systems and technologies
Photoresponsive moieties have been classified as powerful tools in developing drug delivery systems due to their ability to respond to light with great spatial and temporal precision. Among various stimuli, visible light is useful and effective because it is easy to get, doesn't hurt, and gives better control over space and time. A variety of photosensitive drug delivery systems are being used to control where and when drugs are given to improve how well they work and keep people safe. Some photochromic probes can only be used once (because the light causes an irreversible structural change that causes the full dose to be released), while others can be used more than once because they can be switched back and forth between light and dark. Spiropyran-based photoresponsive drug delivery systems, which have attracted a lot of interest because of their unique ability to undergo reversible isomerization between their closed-ring (spiropyran) and open-ring (merocyanine) forms under light irradiation, are especially under focus. This reversible transition allows for drug-controlled release in response to specific wavelengths of light. This review discusses recent developments in the design and fabrication of spiropyran-integrated nanocarriers, such as nanoparticles, hydrogels, micelles, polymers, and photosensitizers. The focus is on the function of these nanocarriers in the delivery of targeted, on-demand, and controlled drugs.
期刊介绍:
Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied.
Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media.
The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
