Fundació URV posted this:NEW PROCEDURE FOR OBTAINING MONOLAYERS OF FUNCTIONALIZED NANOPARTICLESThis new procedure (not described in the bibliography) allows the manufacture of monolayers of metal nanoparticles linked by molecules of organic compounds. As you can see in Specifications, this procedure consists in two successive processes. One of the main advantages of this technology is the minimization of impurities in the functionalized monolayer compared to commonly used techniques. Besides, the manufacture of Schotty diode with this new procedure has been shown for the first time. In the same line, this procedure allows the use of monolayers of metal nanoparticles for metabolite detection. These are two unique and differents aspects of this technology in relation to other known used techniques.

UNIVERSIDAD DE ALICANTE posted this:Novel method to fabricate highly selective sensors for different substances of interestThe research group "Electro catalysis and Electrochemistry of Polymers", Department of Physical Chemistry at the University of Alicante has developed a novel method that allows highly selective electrode manufacture biometrics to detect any biochemical substance of interest, food or environmental. The method is based on the electro assisted deposit of molecularly imprinted silica layers on different electrodes. This allows a fast and efficient detection of the molecule of interest, independently of the other interfering. In addition, allows the regeneration of the electrode in a very simple way and lets its usage almost indefinitely. Innovative aspects The biometrical electrode manufacturing method is based on a electro assisted method of molecularly imprinted silica layers on different electrodes. With this new procedure, we obtain uniform and consistent layers of silica that allow highly selective detection of any biochemical substance of interest, food or environmental when these electrodes are used as amperometric, voltammetric, impedimetric and potentiometric sensors. Main advantatges of the technology The main advantage of the electro assisted deposit respect to conventional methods of thin film deposition (spin-coating or dip-coating), lies in the control of consistency and porosity of the layers. Due to the prevention of uncontrolled pore formation, avoids the indiscriminate passage of species from the solution to the electrode surface, reducing the interference in the detection of the analyte of interest. It has a high specificity and affinity for the molecule of interest. High control on the deposition of silica when is done by electro assisted mode. The possibility of varying the thickness of the silica layer and layer morphology allows for a highly consistent and reproducible layer. Electro assisted deposit method is capable of "self-healing", i.e. prevents the formation of holes in the assisted layer that interfere with the detection of the molecule of interest. With continued use, the sensor loses its effectiveness by the collapse of the pores with the species to be determined. In this case, the regeneration process is very simple: just repeat the procedure for removing the template molecule to be performed after the gel layer (electrochemical extraction or cleaning solvents). Thus, the pores of the sensing phase are released for use again.

In order to maximize the sensitivity of the interferometric laser biosensor, and in order to have an integral and inherent biological reference within the sensor device to account for nonspecific binding, the sensor receptors are immobilized only on the sensing branch. A combined photolithographic-biochemical process was developed to enable the patterning of the sensor receptors on the branch. Project ID : 5-2012-385
