Chitosan, a natural biopolymer sourced from chitin, serves multiple roles in the synthesis and operation of metal nanoparticles and nanocomposites. It functions effectively as an environmentally friendly reducing agent, a stabiliser, and an agent that directs shape and controls particle size during fabrication. These characteristics assist in producing metallic nanomaterials tailored with specific properties. Nanocomposites formulated with chitosan present notable utility across both environmental and healthcare domains. Potential environmental applications include water purification and the removal of dissolved metals from contaminated sources. In healthcare, these composite materials show promise for antibacterial treatments as well as light-based therapies, including photoacoustic, photothermal, and photodynamic treatments. The biopolymer offers a sustainable platform to support developments in nanotechnology directed at solving environmental contamination and advancing therapeutic medical procedures.
Producing nanomaterials often relies on harsh chemicals, making green alternatives vital. Chitosan provides a sustainable route to synthesise metal nanoparticles while simultaneously controlling their size and stability. By enabling cleaner production of materials suitable for purifying polluted water and delivering targeted medical therapies, this biopolymer supports more environmentally benign approaches to technological and clinical challenges.
The material shows relevance for industrial water treatment providers seeking metal removal and purification methods, as well as biomedical developers creating antibacterial, photothermal, or photodynamic therapies. As the abstract describes an overview of potential applications rather than specific deployment data, the work appears to reflect early-stage exploratory research that requires substantial development before reaching market readiness.

Chitosan, a naturally occurring biopolymer derived from chitin, has emerged as a highly promising instrument for the production and application of metal nanoparticles. The present review delves into the several functions of chitosan in the development and operation of metal nanoparticles, emphasizing its aptitudes as a green reducing agent, shape-directing agent, size-controlling agent, and stabilizer. Chitosan's special qualities make it easier to manufacture metal nanoparticles and nanocomposites with desired characteristics. Furthermore, there is a lot of promise for chitosan-based nanocomposites in a number of fields, such as metal removal, water purification, and photoacoustic, photothermal, antibacterial, and photodynamic therapies. This thorough analysis highlights the potential application of chitosan in the advancement of nanotechnology and the development of medicinal and environmental solutions.
