Nanotechnology is a highly interdisciplinary field, with contributions from all fields: physics, chemistry, biology, materials science, engineering, and others. The explosive number of publications in this field makes it nearly impossible to give an extensive review even in chemistry alone. Nonetheless, one may track its emergence and rapid advancement from the point of view of a chemist's. This paper aims to provide a conceptual overview of chemistry for nanotechnology, a brief classification of different approaches and applications, together with some sample cases.

Synthesis of glyceride esters of a fatty acid produces a mixture of isomers that are difficult to separate and analyze, requiring high temperature GC in most cases particularly for long-chain esters. In this paper, we present a fast estimation of the composition of the glyceride esters of lauric acid and glycerol (monolaurin, dilaurin, and trilaurin) by FTIR band shape analysis. The method uses the fact that the carbonyl stretching regions of the pure glycerides have differentband shapes, which implies any composite band of a mixture of glycerides may be resolved into the component peaks due to each glyceride. The carbonyl …
