Janus Catalytic Micromotors: From Mobile Sensors on Lab-on-a-Chips to Mobile Reactors for Tailored Synthesis of NanoparticlesTuesday, 18 June 2019 at 14:15 Add to Calendar ▼2019-06-18 14:15:002019-06-18 15:15:00Europe/London Janus Catalytic Micromotors: From Mobile Sensors on Lab-on-a-Chips to Mobile Reactors for Tailored Synthesis of NanoparticlesLab-on-a-Chip and Microfluidics Europe 2019 in Rotterdam, The NetherlandsRotterdam, The NetherlandsSELECTBIOenquiries@selectbiosciences.com 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. |
