Microcarriers: Elaborate Design Strategies Toward Novel Microcarriers for Controlled Encapsulation and Release (Part. Part. Syst. Charact. 1/2013)
Novel microcarriers for encapsulation of bioactive agents have been extensively investigated for therapeutic applications. Recent advances in microfluidics and other techniques have inspired the design of new microcarriers with precisely controlled size, shape, and function, which possibly allow for new medical and biological applications. Various types of novel microcarriers, including block-copolymer nanoparticles, cylindrical microparticles, dense-shell microcapsules, macroporous microcapsules, polymer vesicles, and foldable bilayer microparticles, are reviewed by Seung-Man Yang and co-workers on page 9.
Colloidal Nanoparticles: Formation of Large 2D Arrays of Shape-Controlled Colloidal Nanoparticles at Variable Interparticle Distances (Part. Part. Syst. Charact. 1/2013)
Substrates with structures at the nanoscale are produced using a method presented by Stefan Kudera and co-workers on page 102. Colloidal nanocrystals are first synthesized in solution and then exposed to a ligand exchange. A monolayer of the particles covered with a thick layer of polystyrene is formed on the substrate. This results in a regular arrangement of the nanoparticles with tuneable interparticle distances. The method is accessible to different shapes and types of nanoparticles.
Janus Particles: Metallic Janus and Patchy Particles (Part. Part. Syst. Charact. 1/2013)
The image shows an artist's view of different types of Janus and patchy particles, with different capping molecules, compositions, or morphologies at different parts of the particles. The partially immersed particles exemplify the preparation methods based on partial surface modification. A summary of the state of the art in the formation, properties, and applications of Janus and patchy particles containing a metallic component is presented by Denis Rodríguez-Fernández and Luis M. Liz-Marzán on page 46.
