DNA‐based chiral selectors are constructed to discriminate ofloxacin enantiomers through metal‐ion anchoring on a special DNA double helix that contains successive GC pairs. The effects of metal ions involving Mg2+, Ni2+, Cu2+, Ag+, and Pt2+ were studied on the regulation of DNA chiral discrimination towards ofloxacin enantiomers. It is shown that DNA‐Cu(II) complexes exhibit the highest enantioselectivities...
Bovine serum albumin (BSA) anchored on the surface of magnetic Fe 3 O 4 nanoparticles (MNPs) were prepared using electrostatic adsorption and studied as a new magnetically chiral selector for the separation of chiral drug enantiomers. It is indicated that the immobilized BSA molecules on the magnetic nanoparticles using electrostatic adsorption retain their stereoselective recognition...
