Silver‐assisted detection: A novel circular dichroism (CD) method was described for detecting L‐cysteine in biological fluids on the basis of chiral nanoparticle self‐assembly from AgI and L‐cysteine (see graphic). The method allows highly selective and sensitive detection of L‐cysteine in biological fluids at the μM level without the need for any special synthesis or sample pretreatment other than...
Water-soluble l-cysteine-capped-CdS nanoparticles were prepared in aqueous solution at room temperature through a straightforward one-pot process by using safe and low-cost inorganic salts as precursors, and characterized by transmission electron microscopy, X-ray diffraction spectrometry, Fourier transform infrared spectrometry, spectrofluorometry and ultraviolet–visible spectrometry. The prepared...
