Polymer crossroads act as tiny reactors

Abstract:
Scientists in the US have taken inspiration from a Dutch painter to create ultrasmall chemical reactors at the junctions of overlapping polymer nanofibres. Their method could eventually be used for high throughput testing of new organic reactions - for as little as seven pence per reaction.

Pavel Anzenbacher Jr and Manuel Palacios, at the Bowling Green State University, have demonstrated that they can incorporate reagents between the threads of separate polymer nanofibres using a well-known technique called electrospinning. These nanofibres can then be laid on top of each other in a mat-like fashion, and the reagents at the 'junctions' activated using heat or solvent vapour. Once activated, the different reagents in the two fibres react with each other to form a product that remains infused within the polymer fibres.
