Reactive Inkjet Printing of Functional Silk Micro-motors – Presented by David Alexander Gregory, The University of Sheffield

Reactive Inkjet Printing of Functional Silk Micro-motors – Presented by David Alexander Gregory, The University of Sheffield, at the 3D Medical Conference, on January 30-31, 2019, MECC Maastricht, The Netherlands

At present many small-scale stirring methods require external actuation, which can be cumbersome. Stirring small volumes of solutions can for example reduce immunoassay readout time. Here, we demonstrate the use of reactive inkjet printing to produce autonomously rotating biocompatible silk-based micro-stirrers capable of enhancing fluid mixing. Two types of propulsion mechanisms are discussed producing rotary motion. Either by release of a surface-active agent resulting in Marangoni effect driven motion, or by catalytically powered bubble propulsion. Marangoni driven devices do not require any additional chemicals to aid propulsion, whereas catalytically powered devices are powered by the decomposition of substrate molecules into the bulk solution. The surface tension driven motors also display great sensitivity to fluid properties and thus the devices show great potential for sensing applications, such as water pollution sensors.
