a–c SEM images of a l-Cys, b d-Cys, and c dl-Cys-Cu2-xS NFs. d CD spectra of thin films of NFs on quartz wafer (l-Cys (red), d-Cys (blue), dl-Cys (black)). Scale bars = 500 nm. e TEM images of the different stages during the NF formation. f CD spectra of the intermediate stages by aging time. g Top view of l-, d-Cys-Cu2-xS NFs models used in computational simulation (ellipsoid shaped nanoleaves stacked counterclockwise for l-Cys and clockwise d-Cys). Scale bars = 500 nm. h Electric field distribution of each layer in d-Cys-Cu2-xS NFs and l-Cys-Cu2-xS NFs model with 1000 nm LCP and RCP. Reproduced with permission from [105].
