Glass substrates functioned by biochemical substances and/or metal thin films have been used for a number of microTAS devices. Nano-structured glass surfaces of the substrates potentially augment the device performance. We propose manufacturing of glass nano particles (NPs) using electrospinning of the sol of tetraethyl orthosilicate (TEOS) containing hydrochloric acid as a catalyst. The size and morphology of the glass NPs were controlled by the applied voltage, the feed speed of the sol, viscosity of the sol and modification of the substrate surface. The proposed dry, non-photolithographic, room-temperature, and atmospheric process is readily applicable to high-performance microTAS devices. We have developed deposition of silver NPs on a glass substrate and applied it to enhanced Raman and fluorescent spectroscopy. We considered that depositing silver NPs on a nano-structured glass surfaces instead of a flat one would lead to greater enhancement of optical signals due to the greater surface areas.
