Biologically Inspired Nanoparticle Synthesis

The intriguing supramolecular architecture of ferritin, as well as its unique functional properties, might be taken as a model for the construction of artificial nanocompartments where crystal growth takes place within a spatially confined microenvironment under controlled conditions. Classical approaches that make use of the entrapped water content of oil-water microemulsions are likewise simple to carry out, but as a rule suffer from relatively broad size distributions of the precipitated nanoparticulate materials. For advanced applications, novel synthetic routes will therefore be required to control the dimensions of the desired inorganic nanoparticles. Examples of technologically important compounds which exhibit strongly size-dependent physical and chemical properties range from catalytically active, highly dispersed metal nanocolloids (e.g. Pt, Pd, Rh), quantum-confined semiconductor nanoparticles (CdS, CdSe) to nano-scale ferrimagnetic particles (e.g. y-Fe2O3) and nanocomposite magnetic alloys. Recent examples of biologically inspired synthetic approaches to synthesize nanoscale inorganic materials include the use of biotechnologically engineered apoferritin shells and virus protein cages (capsids), or the use of monodisperse block copolymer micelles as nanoscale reaction compartments (see Further Reading).

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
