Abstract Enantioselectivity of helical aggregation is conventionally directed either by its homochiral ingredients or introduction chiral catalysis. The fundamental question, then, whether that consists only achiral components can obtain enantioselectivity in the absence Here, exploiting enantiospecific interaction due to chiral-induced spin selectivity (CISS) has been known work enantio-separate a racemic mixture molecules, we demonstrate assembly mesoscale supramolecules consisting cobalt...

An infrared free electron laser (IR-FEL) can decompose aggregated proteins by excitation of vibrational bands. In this study, we prepared hybrid materials protein (human serum albumin; HSA) including several new Schiff base Zn(II) complexes incorporating amino acid (alanine and valine) or dipeptide (gly-gly) derivative moieties, which were synthesized characterized with UV-vis, circular dichroism (CD), IR spectra. Density functional theory (DFT) time dependent DFT (TD-DFT) calculations also...

A salen-type Schiff base Zn(II) complex included in human serum albumin (HSA) protein was examined by UV-Vis, circular dichroism (CD), and fluorescence (PL) spectra. The formation of the composite material also estimated a GOLD program ligand-protein docking simulation. cast film HSA prepared, effects metal on degradation molecules mid-infrared free electron laser (IR-FEL) were investigated. optimum wavelengths IR-FEL irradiation to be used based experimental FT-IR spectra vibrational...
