Recently, we have succeeded in synthesizing amphiphilic silica/polymer Janus microspheres by selectively coating silica nanoparticles on one of their polymer hemispheres. Jeong Won and Jangwoo are working on this fatastic project. After synthesizing uniform Janus polymer microspheres by using the seeded swelling polymerization, they have made another success in fabrication of novel functional Janus colloids. You guys made such a great Job!!!!
