The new emergent properties of nanoparticles include quantam size effect, nonlinear optical properties and thus the nanomaterials have extensive applications in microelectronic, bacteriostatic and catalytic or magnetic recording materials. Nanoparticles find potential applications in DNA detection and photo detection. Gold nano particles (AuNPs) are useful in nanoscale devices and systems due to its resistance to oxidation. In this paper a cost effective, versatile and simple one step room temperature synthesis of highly stable and freestanding Au quantum dots capped by TTAB (Tetradecyltrimethyl Amonium Bromide) in the range of 10-90 nm is reported. Ultraviolet- visible spectroscopy (UV-VIS), Fourier transformation infrared spectroscopy (FT-IR) was carried out to characterize these samples. Scanning Electron Microscopy (SEM) confirms the AuNPs sizes of about 80 and 88 nm.
