Photodynamic therapy (PDT) is an established therapeutic method, first approved by the FDA for certain kinds of cancer in 1998. There are also increasing data to show that a related procedure, sonodynamic therapy (SDT), is a promising new modality for cancer treatment. Here, the authors report clinical results in 3 advanced refractory breast cancer patients who were treated using a combination of sonodynamic and photodynamic therapy (SPDT), along with conventional therapies. All 3 patients had pathologically proven metastatic breast carcinoma. These widely disseminated carcinomas had ultimately failed to respond to conventional therapy. A new sensitizing agent, Sonoflora 1 (SF1) was administered sublingually; then, after a 24-hour delay, patients were treated with a combination of light and ultrasound. All patients had significant partial or complete responses. SPDT is a promising new therapeutic combination for the treatment of breast cancer.

Esophageal cancer is the eighth most common cancer worldwide and the sixth leading cause of cancer-related deaths. In this study, we propose a novel esophageal stent equipped with a wireless, battery-free, and movable photodynamic therapy (PDT) unit designed to treat esophageal tumors with flexibility, precision, and real-time control. This system integrates a PDT unit and an electrochemical pneumatic soft actuator into a conventional esophageal stent.

Photodynamic therapy is an "old" strategy for cancer therapy featuring clinical safety and rapid working, but suitable photosensitizers for colorectal cancer therapy remain lacking. This study synthesized a novel photosensitizer termed Ce6-GFFY based on a self-assembling peptide GFFY and a photo-responsive molecule chlorin e6 (Ce6). Ce6-GFFY forms macroparticles with a diameter of ∼160 nm and possesses a half-life of 10 h, as well as an ideal tumor-targeting ability in mouse models.

Multifunctional nanoparticles for biomedical applications are widely researched and constantly developed because they provide wider possibilities for therapy and diagnostics. This work aims to summarise our findings towards the design of multifunctional complex iron oxide and silver nanoparticles (NPs) produced from the plants and and mushrooms and . It was revealed that the antimicrobial and anticancer properties of the NPs were a consequence of the combination of silver and phyto- and fungo-chemicals originating from natural species.

Cancer continues to pose a formidable challenge in global health due to its incidence and increasing resistance to conventional therapies. A key factor driving this resistance is tumor hypoxia, characterized by reduced oxygen levels within cancer cells. This hypoxic environment triggers a variety of adaptive mechanisms, significantly compromising the efficacy of cancer treatments.

Methicillin-resistant (MRSA), a major cause of fatalities due to Antimicrobial Resistance (AMR), can act as an opportunistic pathogen despite being part of the normal human flora. MRSA infections, such as skin infections, pneumonia, sepsis, and surgical site infections, have risen significantly, with bloodstream infection cases increasing from 21% in 2016 to 35% in 2020. This surge has prompted research into alternative treatments like nanomaterials, photodynamic therapy, antimicrobial peptides (AMPs), and essential oils (EOs).
