: The prevention and treatment of various infections caused by microbes through antibiotics are becoming less effective due to antimicrobial resistance. Researches are focused on antimicrobial nanomaterials to inhibit bacterial growth and destroy the cells, to replace conventional antibiotics. Recently, carbon dots (C-Dots) become attractive candidates for a wide range of applications, including the detection and treatment of pathogens. In addition to low toxicity, ease of synthesis and functionalization, and high biocompatibility, C-Dots show excellent optical properties such as multi-emission, high brightness, and photostability. C-Dots have shown great potential in various fields, such as biosensing, nanomedicine, photo-catalysis, and bioimaging. This review focuses on the origin and synthesis of various C-Dots with special emphasis on bacterial detection, the antibacterial effect of CDots, and their mechanism.

Abstract Background As an emerging nanomaterial, carbon dots (CDs) have been the focus of tremendous attention for biomedical applications. However, little information is available on their bioactivity of inhibiting acute kidney injury (AKI) induced by snake venom. Methods This study reports the development of a green, one-step pyrolysis process to synthesize CDs using Phellodendri Chinensis Cortex (PCC) as the sole precursor, and their potential application as a protectant against Deinagkistrodon acutus (D. acutus) venom-induced AKI was investigated for the first time. The AKI model was established by injecting D. acutus venom into the abdominal cavity of mice and the potential protective effects of PCC Carbonisata-CDs (PCCC-CDs) on renal abnormalities including dysfunction, inflammatory reactions, tissue damage, and thrombocytopenia at six time points (1, 3, and 12 h, and 1, 2, and 5 days) were investigated. Results These results demonstrated that PCCC-CDs significantly inhibited the kidney dysfunction (reduced serum creatinine (SCR), blood urea nitrogen (BUN), urinary total protein (UTP), and microalbuminuria (MALB) concentrations) and the production of chemoattractant (monocyte chemotactic protein 1 (MCP-1)), proinflammatory cytokines (interleukin (IL)-1β), and anti-inflammatory cytokine (IL-10) in response to intraperitoneal injection of D. acutus venom. The beneficial effect of PCCC-CDs on the envenomed mice was similar to that on the change in renal histology and thrombocytopenia. Conclusions These results demonstrated the remarkable protective effects of PCCC-CDs against AKI induced by D. acutus venom, which would not only broaden the biomedical applications of CDs but also provide a potential target for the development of new therapeutic drugs for AKI induced by D. acutus snakebite envenomation.

Abstract Silane-functionalized carbon dots (SiCDs) can be exploited as effective color converting materials for the solid-state light-emitting devices. However, most of SiCDs reported thus far have shown photoluminescence emissions in the blue and green spectral range, which limit them to construct an efficient white light-emitting diodes (WLEDs) due to the lack of long-wavelength emission. Herein, a series of double silane-functionalized carbon dots (DSiCDs) were prepared via a one-step solvothermal method. The results show that the organic functional group of the silane has great influence on the optical properties of DSiCDs and the number of alkoxy group in the silane has great influence on coating properties of DSiCDs. In addition, the DSiCDs prepared by (3-aminopropyl)triethoxysilane and N-[3-(Trimethoxysilyl)propyl]ethylenediamine with molar ratio of 7:3 show excellent optical properties with the maximum emission at 608 nm under 400 nm excitation. Furthermore, they can be completely dried within 1 h at room temperature to form fluorescent coating with high stability and strong adhesion to the substrate. Together with their excellent optical and coating properties, they can be directly coated on LED chips to prepare WLEDs, with a CIE coordinate of (0.33,0.31), color rendering index of 81.6, and color temperature of 5774 K.
