Abstract
The present review focuses on core-shell nanostructures of spherical gold nanoparticles (Au NPs) and biocompatible polymers mainly from the view points of preparation approaches, nanocomposite properties and potential applications for biology. The preparation approaches are assorted into direct-reduction, covalent “graft-to”, “graft-from” approach, surface bonding and physical adsorption. Various biocompatible polymers are involved such as the thermosensitive polymers, pH-responsive polymers, antibiofouling polymers, conductive polymers and several natural polymers. The encapsulating and loading properties, cellular uptake and drug release control, as well as biorecognition, targeting and sensing potential are discussed in connection with biological systems. These polymeric gold nanocomposites will have a great potential in biotechnology and life science but also face enormous challenge in future applications.
Keywords: Nanostructures, gold nanoparticles, biopolymers, core-shell, biology.

From Biodiversity to Chemical Diversity: Focus of Flavonoids
Flavonoids are the largest group of polyphenols, plant secondary metabolites arising from the essential aromatic amino acid phenylalanine (or more rarely from tyrosine) via the phenylpropanoid pathway. The flavan nucleus is the basic 15-carbon skeleton of flavonoids (C6-C3-C6), which consists of two phenyl rings (A and B) and a heterocyclic ...read more
