Amino acid based ionic liquids: A green and sustainable perspective

open access: yesCurrent Opinion in Green and Sustainable Chemistry, 2016
Abstract Chiral and highly functionalized natural amino acids are readily available by renewable methods in high quantities. They can be easily converted into both anions and cations for the synthesis of ionic liquids. This mini review describes the synthesis of amino acid derived ionic liquids (AAILs) with a focus on the most recent developments ...

Optical modulation of high-affinity biomolecules function via photochromic dyes : a step towards an artificial control of biological activity [PDF]

open access: yes, 2008
Prior to this study, there has yet to be a clear demonstration of an artificial control of antibody affinity via photochromic dyes. The research described in this thesis sets out to address this by investigating photochromic dyes and their subsequent ...
