Carbon dots surface chemistry drives fluorescent properties: New tools to distinguish isobaric peptides

Revealing the synergetic interaction between amino and carbonyl functional groups and their effect on the electronic and optical properties of carbon dots

“…Interestingly, the prepared CDs exhibit unique fluorescence properties, thus able to be applied as isobaric peptides detectors. 20 In line with that, Feng et al also reported redshifted PL properties of CDs decorated with amino and carbonyl groups on the CDs surfaces and a high potential to be applied to enable them to act as a detector for Fe 3+ detection. 31 These studies suggested the intriguing PL properties of CDs that are functionalized by amino and carbonyl groups.…”

“…9,[11][12][13][14][15] This knowledge significantly broadens the potential application of CDs in various applications, such as energy conversion, catalysis, and biomedicine. [16][17][18][19][20] For example, as is well known, the absorption peaks of CDs are mainly in the UV and visible light regions. [21][22][23] Then, our groups utilized a large amount of nitrogen source to broaden the CDs' absorption from UV-Vis to the first NIR window region (650-900 nm), which opened a new potential application as a photothermal agent in photothermal therapy.…”

Construction of highly hydrated and mechanically strong anti-fouling coatings for deep-sea probes based on poly(vinyl alcohol) tannic acid zwitterion coatings

“…18 However, zwitterionic polymers' exceptional hydratability also makes it challenging to deposit them onto material surfaces, which has turned into a significant obstacle for their practical application. 19 Immobilization of zwitterionic betaine polymers has been explored as a solution to this issue. Jiang and his co-workers created the polymer by adsorbing PSBMA-block poly(propylene oxide) onto poly(sulfobetaine methacrylate), 20 or through surface-initiated SBMA atom-transfer radical polymerisation (ATRP), 21 on gold and glass surfaces, respectively.…”
