Enhanced bacterial uptake of 131I -labeled antimicrobial imidazolium bromide salts using fluorescent carbon nanodots

Unlocking the full potential of citric acid-synthesized carbon dots as a supercapacitor electrode material via surface functionalization

“…4,23 Additionally, it was observed that the CDs exhibited distinct shoulder peaks at 335 nm and broad bands at approximately 400 nm, which are indicative of the n–π* electronic transition of CO bonds and the n–π* transitions of the surface/molecule center, respectively. 22,24,25 The surface modification of CDs using bis-MPA HBP resulted in a blue-shift of the maximum emission from 490 nm to 459 nm when excited at 365 nm (Fig. 1e).…”

Carbon Dots as an Emergent Class of Antimicrobial Agents

“…Nitrogen (as well as different heteroatoms such as P, O, and S) has also been incorporated during the CD synthesis using a mixture of different starting materials [ 61 ]. For example, the addition of polyamines [ 16 , 62 ], amino acids [ 63 , 64 , 65 , 66 , 67 ], or biomass such as plant leaves and fungi [ 68 , 69 , 70 , 71 , 72 , 73 , 74 ], food [ 75 , 76 , 77 , 78 , 79 ], and industrial [ 80 ] and waste derivatives [ 81 , 82 ], among others, have been used for the preparation of doped CDs. In this context, two independent comparative studies from the Kang [ 83 ] and Bandosz [ 84 ] research groups highlighted that N- or S-doped CDs exhibit very different antibacterial properties.…”
