Green Synthesis of Highly Fluorescent Carbon Dots from Bovine Serum Albumin for Linezolid Drug Delivery as Potential Wound Healing Biomaterial: Bio-Synergistic Approach, Antibacterial Activity, and In Vitro and Ex Vivo Evaluation

“…However, after the hydrothermal carbonization process, the FT-IR spectrum of BCDs nano-biocarrier became simpler and the absorption bands were slightly shifted due to the altered chemical environment ( Figure 2 ). Many characteristic bands were still found in the FT-IR spectrum of BCDs nano-biocarrier, which correspond to –OH/–NH broadband at 3600–3299 cm −1 , aliphatic –CH stretching at 2969 and 2933 cm −1 , carbonyl (C=O) stretching at 1667 cm −1 , C=C stretching at 1463 cm −1 , C–N stretching at 1401 cm −1 , C–O stretching at 1303 cm −1 , and symmetric stretching vibration of C–O–C at 1102 cm −1 [ 38 ]. The absorption bands of both the carbonyl (C=O) stretching and the C–O stretching together indicate the existence of the –COO– functional group [ 39 ].…”

“…The CQDs were employed as staining agents for the HeLa cancer cell via both active and passive targeting. Sahu et al [ 86 ] have fabricated CQDs with citric acid, urea, and boric acid via microwave-assisted synthesis. Furthermore, the as-prepared CQDs were submitted to surface modification with bovine serum albumin (BSA), promoted by continuous stirring for 24 h. Since BSA is a native fluorescent molecule, fluorescence bands at 444 nm and around 300 nm were observed, caused by CQDs and BSA modified CQDs, respectively.…”
