A fast and sensitive method was developed for the determination of the absolute configuration of selenomethionine. The enantiomers of selenomethionine were converted into diastereomeric isoindole derivatives by reaction with o-phthaldialdehyde and N-isobutyryl-L-cysteine. This easy-to-handle reaction proceeds quantitatively in a few

All-atomistic molecular dynamics simulations with explicit water solution are performed to investigate the interaction between single-stranded DNA (ssDNA) molecules and chiral N-isobutyryl-cysteine (NIBC) molecule coated Au surfaces. Different contributions to the force exerted on ssDNA are analyzed. It turns out
