Showcasing work from D. M. Eisele and coworkers, The City College of New York at The City University of New York, USA. Microfluidic-supported synthesis of anisotropic polyvinyl methacrylate nanoparticles via interfacial agents By combining the advantages of microfluidics and bulk batch synthesis, D. M. Eisele and coworkers developed a single-step, microfluidic supported synthesis for anisotropic polyvinyl methacrylate (PVMA) polymer nanoparticles with dimensions ranging from 50 nm–200 nm. The cover highlights a SEM image of flower-shaped polyvinyl methacrylate (PVMA) nanoparticles. The research was performed at the NSF Center of Research Excellence in Science and Technology (CREST) for Interface Design and Engineered Assembly of Low Dimensional Systems (IDEALS) at The City College of New York at The City University of New York, USA.
