Abstract: Disclosed is an olfaction system based on integration of gas sensitive conducting polymers and Floating Gate Metal Oxide Semiconductor (FGMOS) sensors. A sensing polymer, polypyrrole for example, is electrochemically deposited onto sensor pads which are electrically connected to floating gate of the sensor. The response of these sensing polymers to any vapour analyte can be tailored using several techniques that include the use of different dopants, changing electrolyte concentrations or varying growth potential at the time of electrodeposition. Using an array of floating gate sensors, coupled to these chemically diverse polymers, this system will facilitate a signature-like response from the sensors in the array. Every sensor can be accessed and analysed individually using a specially designed addressing circuit. The response from the sensors is amplified through a trans-impedance amplifier and converted to 8-bit digital data for ease of analyte identification and quantification.

Abstract: The present invention relates to a nanoparticulate topical composition comprising (i) nanoparticles of a water soluble and water susceptible active ingredient or its pharmaceutically acceptable salt, having a particle size distribution such that 90% of the particles are less than 1000 nm, (ii) one or more wetting agent and (iii) a non-aqueous liquid vehicle, wherein the composition is free of water. The present invention also relates to a method of treating acne, rosacea, impetigo or a skin disease caused by a bacteria, by topical application of a nanoparticulate topical composition comprising nanoparticles of a water soluble and water susceptible active ingredient or its pharmaceutically acceptable salt, having a particle size distribution such that 90% of the particles are less than 1000 nm.
