A recent article by CIQUS researchers Felix Freire and José Manuel Seco, who belongs to the Research Group of Ricardo Riguera and Emilio Quiñoá, has been selected both front cover of the last issue and spotlight on the recent JACS publications (Journal of the American Chemical Society).
This work describes a new nanospheres with Tunable Size and Chirality from Helical Polymer–Metal Complexes.
This new family of nanospheres made by complexation of divalent metals and poly(phenylacetylene) polymers, present two interesting properties: (a) their diameter can be tuned to different sizes by changing the metal ion or the polymer/metal ion ratio, and (b) the helicity of the particle can be tuned to any of the two helical senses (M or P) by selection of the metal ion. The ability of these nanospheres to encapsulate is also demonstrated with examples as iron oxide magnetic nanoparticles, quantum dots and fluorescent dyes.
Nanospheres formed by supramolecular self-assembly are of great interes to chemists for encapsulating functional molecules for later delivery. They can be used in a variety of technologies, such as drug-delivery, cosmetics, and nanoreactors.
This article is the continuation of other two already published works on the world-renowned journal Angewandte Chemie during 2010 and 2011. All of them are part of the research line about sensors based on stimuli-responsive polymers.
