ABSTRACT

One of the fascinating aspects of nanoscience and nanotechnology

is that the nanoworld is full of surprising structures and features

that one would not have imagined. There have been a number of

significant developments that have enabled scientists to explore

the world with nanoscale objects. These developments include

the development of various types of microscopes, techniques for

nanomanipulation, and methods of nanofabrication. This chapter

is devoted to discussions of the various types of microscopes, fol-

lowed by optical tweezers and techniques of nanofabrication. The

chapter starts off with a discussion on traditional optical micro-

scope, followed by the scanning electron microscope and trans-

mission electron microscope. Next we focus on the development

and working principles of the scanning tunneling microscope

and atomic force microscope. The optical tweezer technique, a

technique commonly used for the trapping and manipulation of

micro/nanoparticles in aqueous suspension, is then introduced.

Finally, we present a method for nanofabrication by means of

focused laser beams.
