Janus Catalytic Micromotors: From Mobile Sensors on Lab-on-a-Chips to Mobile Reactors for Tailored Synthesis of Nanoparticles

Alberto Escarpa Miguel, Professor, University Of Alcala

Micromotors represent one of the most exciting horizons in micro and nanotechnologies. Micrometer-sized motors can either have a conical tubular or spherical structure. Spherical shapes comprise Janus micromotors (named after the two-faced Roman god Janus); which are prepared by asymmetrically coating of microparticles (silica, polystyrene) with a catalytic layer (mainly Pt) for decomposition of a fuel (mainly hydrogen peroxide) towards efficient propulsion. If they are used with creativity, they offer also considerable promise for labs-on-a-chip applications in both approaches: analysis and synthesis.

In this keynote, the truly two faces of Janus catalytic micromotors, analysis and synthesis, towards two relevant approaches will be presented and discussed.

On a first approach, the use of magneto-catalytic Janus micromotors encapsulating phenylboronic acid and graphene quantum dots as mobile sensors for detection of bacteria endotoxins in lab-on-a-chip devices, will be discussed. A second approach will illustrate the tailored synthesis of CdS quantum dots and Au nanoparticles nanoparticles with “mobile” catalytic Janus micromotors encapsulating suitable precursors (Cd2+ or citrate).  Both approaches hold considerable promise for diverse clinical, agro-food and biological lab-on-chip applications.
