Formulation of Silver Nanoparticles of Hibiscus Sinesis Herbal Extract by UV Spectroscopy

For the past few decades, there has been a considerable research interest in particulate delivery systems. So, particulate systems like nanoparticles have been utilized as physical approaches to change and improve the pharmacokinetic and pharmacodynamics properties of various types of drug molecules. Different types of Nano particulate materials used in electronics, magnetic pharmaceuticals, cosmetics, energy, catalytic and materials industries. Nanoparticles are tiny materials having size ranges from 1 to 100 nm. They can be classified into different classes based on their properties, shapes or sizes. The nanoparticles show enhanced properties such as high reactivity, strength, surface area, sensitivity, stability, etc. Because of their small size. The nanoparticles are synthesized by various methods for research and commercial uses that are classified into three main types namely physical, chemical and mechanical processes that has seen a vast improvement over time. This paper presents a review on nanoparticles, their types, properties, synthesis methods and its applications.
