Best poster award for work on nanoparticle synthesis using microreactor at Indian Conference

The poster entitled “Gold nanoparticle synthesis at room temperature using microreactor” won the first prize of best poster at the International Conference on Nanoscience and Nanotechnology which took place in Gurgaon, India from December 17th to 21st 2007 (Authors: Akanksha Singh², Chantal Khan Malek*, and S. K. Kulkarni²). This poster results from the French-Indian collaboration initiated between FEMTO-ST (*) and the University of Pune (²) and funded under the IFCPAR programme (Project: 3408-1).
Abstract: Chemical synthesis in microreactor is a novel way of conducting chemistry and offers potential advantages in term of continuous flow, lower amount of solvents, faster reactions, minimal waste and better control over reaction as well as possibility of parallelization. The synthesis of gold nanoparticles, a well known reaction in batch format, was performed successfully in aqueous solution at room temperature in a PDMS microreactor. The reaction time in microreactor format was much faster (on the order of 5 min) than the reaction time in a macroscopic reactor (from 30 min to 1 hour). Studies as a function of temperature and reducing agent concentration were conducted.
