Fluorescence experiments were performed with a Hitachi F-4600 fluorescence spectrometer (Hitachi, Japan) with excitation at 380 nm and emission at 450 nm. Fourier transform infrared spectroscopy (FT-IR) spectra were recorded in the wavelength range of 4000–500 cm−1 with a Nicolet Avatar 360 FT-IR spectrophotometer (Thermo Fisher Scientific, USA). To study the morphology and estimate the mean diameter of the resultant GSH–Cu/Au BNCs, transmission electron microscopy (TEM) analyses were conducted on a JEOL-2100F transmission electron microscope (Japan) operating at an accelerating voltage of 200 kV. UltimaIV Powder X-ray diffraction (XRD) patterns were recorded using an X-ray diffractometer (Rigaku, Japan) operating at an accelerating voltage of 40 kV.

(UV–vis) absorption spectra and fluorescence spectrum were
recorded using a Hitachi U-2900 (Hitachi, Japan) UV–vis spectrophotometer
and a Hitachi F-4600 (Hitachi, Japan) fluorescence spectrophotometer,
respectively. The images of transmission electron microscopy (TEM)
were taken using a JEOL-2100F transmission electron microscope (Japan)
to probe the surface morphology and assess the average diameter of
N-GQDs. Fourier transform infrared (FT-IR) spectra were characterized
using a Nicolet Avatar 360 FT-IR spectrophotometer (Thermo Fisher
Scientific). X-ray diffraction patterns were measured using an X-ray
diffractometer (Rigaku, Japan). X-ray photoelectron spectroscopy (XPS)
data were collected by a Thermo Scientific ESCALab 250Xi. The fluorescence
lifetime was measured with an Edinburgh Instruments FLS980 fluorescence
spectrophotometer with excitation at 360 nm.

The preparation of Fmoc-FF-OFm, Fmoc-FFF-OFm and Fmoc-FFFF-OFm peptides was carried out following standard procedures of peptide synthesis in solution starting from the corresponding F-derivative and using the Boc or Fmoc group as protection for the amino moieties. A general procedure for the coupling reactions is given in Figure 1.
Melting points were determined on a Gallenkamp apparatus and are uncorrected. IR spectra were registered on a Thermo Nicolet Avatar 360 FTIR spectrophotometer; max is given for the main absorption bands. 1 H and 13 C NMR spectra were recorded on a Bruker AV-400 or ARX-300 instrument at room temperature unless otherwise indicated and using the residual solvent signal as the internal standard; chemical shifts (δ) are expressed in ppm and coupling constants (J) in Hertz. Optical rotations were measured on a JASCO P-1020 polarimeter. High-resolution mass spectra were obtained on a Bruker Microtof-Q spectrometer.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
