Abstract: The present invention refers to an apparatus and method for producing non-woven nanofibers from polymers. The method for producing non-woven micro nanofibers from polymers comprises the use of electrospinning and melt blowing elements. The apparatus presented for producing non-woven micro and/or nanofibers from polymers comprises a source of compressed gas, a pressure gauge, a hypodermic syringe with a pump for controlling the injection rate of the polymeric solutions, a pulverizing apparatus and a collector preferably with controlled rotation speed. The technology presented for producing non-woven micro and/or nanofibers is capable of producing micro and nanofibers having diameters similar to those produced by electrospinning, also on an industrial scale. The invention also comprises the use of non-woven nanofibers in pulverizing live tissues and as coating for materials.

Abstract: The object of the present invention is to provide a means of detection and evaluation of mixtures, based on the concept of global selectivity, with enhanced sensitivity and selectivity. A first embodiment refers to a sensor for the analysis of mixtures by global selectivity comprising at least two sensor units consisting of: (a) interdigitated electrodes or microelectrodes sheathed with at least one monolayer of an ultra-fine film of a membrane forming material possessing physicochemical affinity for the substances peculiar to the mixture to be analysed selected from the group consisting of complexing polymer conductors, complexing substances and combinations thereof and, optionally, (b) non-sheathed interdigitated electrodes or microelectrodes.
