Phloroglucinol-Based Carbon Quantum Dots/Polyurethane Composite Films: How Structure of Carbon Quantum Dots Affects Antibacterial and Antibiofouling Efficiency of Composite Films

Polymers, Journal Year: 2024, Volume and Issue: 16(12), P. 1646 - 1646

Published: June 11, 2024

Nowadays, bacteria resistance to many antibiotics is a huge problem, especially in clinics and other parts of the healthcare system. This critical health issue requires dynamic approach produce new types antibacterial coatings combat various pathogen microbes. In this research, we prepared type carbon quantum dots based on phloroglucinol using bottom-up method. Polyurethane composite films were produced swell–encapsulation–shrink Detailed electrostatic force viscoelastic microscopy revealed inhomogeneous structure characterized by electron-rich/soft electron-poor/hard regions. The uncommon photoluminescence spectrum core had multipeak structure. Several tests confirmed that singlet oxygen. Antibacterial antibiofouling efficiency was tested eight strains three biofilms.

Biocompatible Carbon Dots/Polyurethane Composites as Potential Agents for Combating Bacterial Biofilms: N-Doped Carbon Quantum Dots/Polyurethane and Gamma Ray-Modified Graphene Quantum Dots/Polyurethane Composites

Pharmaceutics, Journal Year: 2024, Volume and Issue: 16(12), P. 1565 - 1565

Published: Dec. 6, 2024

Background: Pathogen bacteria appear and survive on various surfaces made of steel or glass. The existence these in different forms causes significant problems healthcare facilities society. Therefore, the surface engineering highly potent antimicrobial coatings is important 21st century, a period that began with series epidemics. Methods: In this study, we prepared two types photodynamic polyurethane-based composite films encapsulated by N-doped carbon quantum dots graphene irradiated gamma rays at dose 50 kGy, respectively. Further, investigated their structural, optical, antibacterial, antibiofouling biocompatibility properties. Results: Nanoelectrical nanomechanical microscopy measurements revealed deviations structure polyurethane films. Young’s modulus elasticity was several times lower than for single-walled nanotubes (SWCNTs) chirality (6,5). electrical properties were quite similar to those SWCNTs much more elastic smoother dots. Antibacterial tests indicated excellent antibacterial activities against wide range tested bacteria, whereas both showed best results Staphylococcus aureus Escherichia coli biofilms. Biocompatibility studies neither film exhibited any cytotoxicity hemolysis. Conclusions: Obtained indicate could be used as facilities.
