Because various non-parallel G-quadruplexes of human telomeric sequences in K+ solution can be converted to a parallel G-quadruplex by adding polyethylene glycol (PEG) as a co-solvent, we have taken advantage of this property of PEG to study the covalent attachment

Galectins, or beta-galactoside binding lectins, are detected deep in tumor tissue and are recognized as diagnostic and prognostic markers of cancer and other serious diseases. There is a need to develop a faster, easier, and simpler method for detecting galectins.

We describe here light-regulated swelling and degradation features of polymeric nanoparticles that are produced using an inverse microemulsion polymerization method. We demonstrate the phototriggered release characteristics of the nanoparticles by sequestering protein molecules and releasing them using light as a
