a Handedness of PDA obtained with all four possible combinations. Left-handed PDA is obtained using 254 nm irradiation assisted with L-Cys@NPs or 313 nm irradiation assisted with D-Cys@NPs. Right-handed PDA is obtained using 254 nm irradiation assisted with D-Cys@NPs or 313 nm irradiation assisted with L-Cys@NPs. b CD spectra showing that chirality of PDA is reversed using (i) l- and (ii) d-Cys@AgNPs upon irradiated with 254 nm unpolarized light. c CD spectra showing that chirality of PDA is reversed using (iii) 313 nm irradiation instead of (i) 254 nm unpolarized light in the presence of L-Cys@AgNPs.
