Synthesis, Cellular Delivery and In vivo Application of Dendrimer-based pH Sensors Lorenzo Albertazzi1, Barbara Storti2, Marco Brondi2, Sebastian Sulis Sato2, Gian Michele Ratto3, Giovanni Signore4, Fabio Beltram2 1Institute for Complex Molecular Systems & Laboratory of Macromolecular and Organic Chemistry, Eindhoven University of Technology & NEST, Scuola Normale Superiore and Istituto Nanoscienze-CNR, 2NEST, Scuola Normale Superiore and Istituto Nanoscienze-CNR & IIT@NEST, Center for Nanotechnology Innovation, 3NEST, Scuola Normale Superiore and Istituto Nanoscienze-CNR, 4IIT@NEST, Center for Nanotechnology Innovation Fluorescence sensors are powerful tools in life science. Here we describe a methodology to synthesize and use dendrimer-based fluorescent sensors to measure pH in living cells and in vivo. The dendritic scaffold enhances the properties of conjugated fluorescent dyes leading to improved sensing properties.
Fabrication, Operation and Flow Visualization in Surface-acoustic-wave-driven Acoustic-counterflow Microfluidics Marco Travagliati1,2, Richie Shilton1, Fabio Beltram2, Marco Cecchini2 1NEST Center for Nanotechnology Innovation, Istituto Italiano di Tecnologia, 2NEST, Scuola Normale Superiore and Istituto Nanoscienze-CNR In this video we first describe fabrication and operation procedures of a surface acoustic wave (SAW) acoustic counterflow device. We then demonstrate an experimental setup that allows for both qualitative flow visualization and quantitative analysis of complex flows within the SAW pumping device.
