Nanomicelles: An Overview

Abstract

Nanomicelles are around 5 to 100 nm in diameter. They are formed by diphilic surfactant molecules or ions formed spontaneously in their solutions at a definite concentration. The micelles may contain hundred or more ions clumped together with a considerable number of water molecules. Micelles are characteried by the aggregation number i.e. the number of molecules in a micelle and the micellar mass.  Interior of these cells are made up of nonpolar groups and the exterior by polar groups. Nanomicelles can be used as hydrophilic and hydrophobic agents. Micelle formation is a spontaneous process. This is entropy controlled .In solvation of individual units, the individual molecules enter inside solvent cages. Once micelle is formed, solvent molecules form a single cage and the forced order is destroyed. They can be used in cancer treatment, several skin diseases and also for eye treatment.  In this paper we want to tell about their types, some properties and their important uses which made them important in modern science.
