The analysis behind the developed sensor has been revealed in Nature Scientific Reports Journal and has been acknowledged as one of many prime 100 in chemistry. The analysis was led by Prof. S. Pushpavanam, Institute Chair Professor, Department of Chemical Engineering, IIT Madras and Dr. T. Renganathan, Associate Professor, Department of Chemical Engineering, IIT Madras.
“We use a standard laser printer with none modification and it affords excessive decision and accuracy. The hydrophobic obstacles are suitable towards natural solvents and excessive temperature. The developed laser printed paper-based microfluidic sensor is a viable choice for giant scale manufacturing and allows routine monitoring of pollution in each developed and useful resource constrained areas,” stated Dr. T. Renganathan.
The analysis was funded beneath ‘Indo UK Water Quality Research Programme’ by Department of Science and Technology (DST), Government of India, UK’s Natural Environment Research Council and Engineering and Physical Sciences Research Council (EPSRC).
Prof. S. Pushpavanam, Institute Chair Professor, Department of Chemical Engineering, IIT Madras, stated, “Paper-based sensor affords an inexpensive platform for numerous point-of-care purposes as they help fluid stream based mostly on a wicking motion and ruled by capillary forces. This eliminates the requirement of a pump-to-flow liquids. We have provide you with a novel methodology for the fabrication of paper- based mostly gadgets utilizing a business laser printer.”
“The method it really works is that we use a porous substrate resembling paper, which allows us to use customary software program to print required designs on it. Once printed, the printer ink is deposited on the floor of the paper. When heated this penetrates the thickness of the paper and kinds a hydrophobic barrier by way of which liquid can’t go. This permits us to direct the stream of liquid in preferential instructions by way of the areas which aren’t printed and are hydrophilic,” added Prof. Pushpavanam.
