BIOSYNTHESIZED NANO PARTICLES BASED TEXTILE COMPOSITE: QUALITATIVE & QUANTITATIVE IMPACT ANALYSIS FOR END USE APPLICATION

Particulate dispersions or solid particles with a size below 100nm are categorised as nanoparticles. They inherently possess superior properties than bulk material in terms of mechanical strength, thermal stability catalytic activity, electrical conductivity, magnetic properties, optical properties, surface properties, etc. which make their end use application area much wide. Popularly used metal nanoparticles in various fields, such as textile, biomedical, health care, food agriculture, industrial, electronics, renewable energy, environment, etc. are silver, gold, copper, alumina, titanium dioxide, zinc oxide. They can be synthesised either of chemical, physical, mechanical or biological method. However, the chemical, physical and mechanical methods have major drawbacks of toxicity, high cost and high energy. Against that biological method is safe, cheaper and consumes less energy. The source material used in this synthesis process is normally plants, fungi, yeast, actinomycetes, bacteria, etc. and system is also classified accordingly. Hence nanoparticles are usually reinforced in base material to enhance its functional characteristics required, and such nanocomposites can be used more preferentially by end users. Cosmetic, medical, photo thermal therapy, drug delivery, biosensors, cancer therapy, imaging, antimicrobial agent, etc. are some of the identified domains of end users.
