Rib fracture-related infection is a challenging complication of thoracic trauma due to the difficulty of treating it with antibiotics alone and the need for a second operation to remove the infected fixator and sterilize the surrounding infected tissue. In this study, inspired by the photocatalytic performance of and ion release from silver-based materials, including AgPO and AgS, a hybrid AgPO-AgS heterojunction was prepared based on anion exchange and a one-step calcination process to design a nonantibiotic coating aimed at preventing and treating rib fracture-related infection with short-term 808 nm near-infrared irradiation. Calcination at 250 °C enhanced the inductive effect of the phosphate radical and led to the formation of a tight nanoheterogeneous interface between AgPO and AgS, thereby promoting interfacial electron transfer and reducing the recombination of photogenerated carriers.

Background: Breast carcinoma stands out as the most widespread invasive cancer and the top contributor to cancer-related mortality in women. Nanoparticles have emerged as promising tools in cancer detection, diagnosis, and prevention. In this study, the antitumor and apoptotic capability of silver nanoparticles synthesized through Scrophularia striata extract (AgNPs-SSE) was investigated toward breast cancer cells.

The rise of antibiotic-resistant Gram-positive bacterial infections poses a significant threat to public health, necessitating the exploration of alternative therapeutic strategies. A photosensitizer (PS) can convert energy from absorbed photon into reactive oxygen species (ROS) for damaging bacteria. This photoinactivation action bypassing conventional antibiotic mechanism is less prone to resistance development, making antibacterial photodynamic therapy (aPDT) highly efficient in combating Gram-positive bacteria.

Herpes simplex virus (HSV) infection is one of the most prevalent viral infections worldwide. In general, host immunity is sufficient to clear viral shedding and recurrences, although it is insufficient to prevent subsequent virologic reactivations. In immunocompromised patients, prolonged and difficult-to-treat HSV infections may develop.
