Plasmonic Nanozyme of Graphdiyne Nanowalls Wrapped Hollow Copper Sulfide Nanocubes for Rapid Bacteria‐Killing

Advanced Functional Materials, Journal Year: 2022, Volume and Issue: 32(20)

Published: Feb. 9, 2022

Abstract Plasmon stimulation represents an appealing way to modulate enzyme mimic functions, but utilization efficiency of plasmon excitation remains relatively low. To overcome this drawback, a heterojunction composite based on graphdiyne nanowalls wrapped hollow copper sulfide nanocubes (CuS@GDY) with strong localized surface resonance (LSPR) response in the near‐infrared (NIR) region is developed. This nanozyme can concurrently harvest LSPR induced hot carriers and produce photothermal effects, resulting dramatically increased peroxidase‐like activity when exposed 808 nm light. Both experimental results theoretical calculations show that remarkable catalytic performance CuS@GDY due unique hierarchical structure, narrow bandgap GDY nanowalls, effect CuS nanocages, fast interfacial electron transfer dynamics, carbon vacancies CuS@GDY. plasmonic exhibits rapid, efficient, broad‐spectrum antibacterial ( > 99.999%) against diverse pathogens (methicillin‐resistant Staphylococcus aureus , Escherichia coli ). study not only sheds light mechanism nanozyme‐/photocatalysis coupling process, also opens up new avenue for engineering NIR driven nanozymes rapid synergistic photo‐enhanced therapy.

Engineered Bacteria for Enhanced Radiotherapy against Breast Carcinoma

ACS Nano, Journal Year: 2022, Volume and Issue: 16(1), P. 801 - 812

Published: Jan. 14, 2022

Radiotherapy is widely applied for multiple malignant tumors ablation in the clinic. However, redundant doses of X-rays might destroy normal tissue periphery tumor sites. Here, we developed an integrated nanosystem (Bac@BNP) composed engineered bacteria (Bac) and Bi2S3 nanoparticles (BNPs) sensitizing radiotherapy. Bac could target colonize sites alternatively, which overexpressed cytolysin A (ClyA) protein to regulate cell cycle from a radioresistant phase radiosensitive phase. Simultaneously, peptide-modified BNPs, as radiosensitizer with high-Z element, was released surface owing matrix metalloproteinase-2 (MMP-2) response microenvironment. Under X-ray irradiation, BNPs enhance radiotherapy sensitivity by triggering intracellular generation reactive oxygen species (ROS), coupled DNA damage. In this constructed nanosystem, combination Bac@BNP irradiation led significant suppression breast carcinoma murine models reduced side effects.

Abstract Esophageal squamous cell carcinoma (ESCC) is the sixth most common cause of cancer-related mortality worldwide, with more than half them occurred in China. Radiotherapy (RT) has been widely used for treating ESCC. However, radiation-induced DNA damage response (DDR) can promote release cytokines and chemokines, triggers inflammatory reactions changes tumor microenvironment (TME), thereby inhibiting immune function causing invasion metastasis Radioresistance major disease progression cancer, it associated heterogeneity. Therefore, a better understanding radioresistance mechanisms may generate reversal strategies to improve cure rates survival periods ESCC patients. We mainly summarized possible order reveal new targets therapy. Then we compared current reverse radioresistance.
