Keywords: Nanostars; nanodiscs; nanorods; nanoflowers.
Nanomaterials of interesting shapes such as nanostars, nanodiscs, nanorods and nanoflowers are frequently synthesized by chemists, experimental physicists and material scientists nowadays. Large number of the bottom-up or top-down synthetic techniques are invented and reported for the synthesis of these materials with interesting shapes. Such shapes found to already exist in nature. The great nature has done this nano artwork with its power and unbeatable architectural skills at molecular level. The ultimate aim of the synthesis techniques invented may not be to mimic nature or challenge it but instead to explore the use of these variously shaped nanomaterials in technological and biomedical applications. These materials found to be applicable in their use as drug delivery systems, catalysis, and energy and as biosensors. In the present note some of the recent examples of such materials are discussed with their images taken with high resolution microscopes.
