Molecularly Imprinted Membranes

A completely different approach for the preparation of affinity membranes is the use of molecu-larly imprinted polymeric materials. These are produced by polymerization of functional and cross-linking monomers in the presence of the target molecule (the molecule to be separated later), which acts as a molecular template. In this way, binding sites are introduced in the polymer that are complementary in shape and functionality to the target molecule, and that often have specificities comparable to those of antibodies. At the same time, the cross-linked polymeric material provides a porous, chemically and physically very stable support. Even though the technology is in principle applicable to larger bio-molecules such as proteins, it has mainly been used for the separation of small molecules like amino acids and peptides. The molecular imprinting technique is reviewed in more detail elsewhere.

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.
