Antibiotics play an important role in the treatment of diseases, but bacterial resistance caused by their widespread and unreasonable use has become urgent problem clinical treatment. With rapid advancement nanoscience nanotechnology, development nanomedicine been transformed into a new approach to resistance. As type carbon-based nanomaterial, carbon dots (CDs) have attracted interest antibacterial researchers due ease preparation, amphiphilicity, facile surface functionalization, excellent optical properties, among other properties. This article reviewed synthesis methods properties various CDs composites order highlight advancements field CDs-based agents. Then we focused on relationship between principal mechanism, including following: (1) physical damage small size, charge CDs. (2) Photogenerated electron transfer characteristics that produce reactive oxygen species (ROS) themselves or compounds. The ability ROS oxidize can lead lipid peroxidation cell membranes, as well proteins DNA. (3) nano-enzyme catalyze reactions generate ROS. (4) Synergistic effect antibiotics nanocomposites. Finally, look forward challenges nanocomposites face practical applications propose corresponding solutions further expand application potential nanomaterials infectious particularly drug-resistant infections.

Methylene Blue-Doped Carbonized Polymer Dots: A Potent Photooxygenation Scavenger Targeting Alzheimer’s β-Amyloid

ACS Applied Materials & Interfaces, Год журнала: 2023, Номер 15(37), С. 44062 - 44074

Опубликована: Сен. 8, 2023

The abnormal aggregation of β-amyloid protein (Aβ) is one the main pathological hallmarks Alzheimer's disease (AD), and thus development potent scavengers targeting Aβ considered an effective strategy for AD treatment. Herein, photosensitizer-doped carbonized polymer dots (PS-CPDs) were synthesized by a one-step hydrothermal method using photosensitizer (PS) o-phenylenediamine (oPD) as precursors, furtherly applied to inhibit via photooxygenation. inhibition efficiency such PS-CPDs can be adjusted varying type photosensitizer, among them, methylene blue-doped (MB-CPDs) showed strongest photooxygenation capability. results demonstrated that under 650 nm NIR light irradiation, MB-CPDs (2 μg/mL) produced reactive oxygen species (ROS) efficiently fibrillization disaggregate mature fibrils increased cultured cell viability from 50% 83%. In vivo studies confirmed extended lifespan nematodes 4 days. Notably, inhibitory capability much stronger than MB previously reported dots. This work indicated carbon obtained have provided new insights into design nanomaterials in
