Platinum supramolecular complexes based on photosensitizers have garnered great interest in photodynamic therapy (PDT) due to Pt (II) centers as chemotherapeutic agents eliminate tumor cells completely, which greatly improve the antitumor efficacy of PDT. However, comparison precursor photosensitizer ligand, formed platinum typically exhibit inferior outcomes terms reactive oxygen species (ROS) generation. How boost ROS generation for enhanced PDT is an enticing yet highly challenging task. Here we report a Pt-coordination-based dimeric complex (Cz-BTZ-Py)

Abstract Based on the properties of photodynamic therapy (PDT) and magnetic resonance imaging (MRI), combining them to construct multifunctional nanotheranostics can leverage strengths avoid weaknesses for tumor diagnosis treatment. However, certain problems remain unsolved, notably short observation window caused by insufficient retention time. In this study, a GSH‐responsive shape‐transformable Gd‐Ce6‐FFVLGGGC‐SS‐PEG are designed (abbreviated as GdCFS) single metal Gd with Ce6, peptide (Phe‐Phe‐Val‐Leu‐Gly‐Gly‐Gly‐Cys) disulfide‐conjugated polyethylene glycol (PEG) perform dual‐modal T 1 /T 2 MRI specifically at site. Due its amphiphilic features, GdCFS self‐assemble spherical nanoparticles, while transforming nanofibers (NFs) in presence intracellular overexpressed GSH stimuli. After NFs formation, hydrophobic core is exposed, resulting positive contrast enhancement, whereas simultaneously achieve negative enhancement. Furthermore, depletion cause imbalance redox state, ultimately improving PDT efficacy. benefits from shape‐transformation terms sufficient time, thus positively minimizing toxicity risk. On model nasopharyngeal carcinoma, vivo vitro outcomes confirm that be promising candidate early diagnosis, real‐time monitoring, precise treatment tumors great biocompatibility.

Bioinspired photoactive composites, in terms of photodynamic inactivation, cost-effectiveness, and biosafety, are promising alternatives to antibiotics for combating bacterial infections while avoiding antibacterial resistance. However, the weak membrane affinity substrate lack synergistic effect remain crucial shortcomings their applications. Herein, we developed a hydrophobic film from food antioxidant lauryl gallate covalently functionalized chitosan (LG-g-CS conjugates) through green radical-induced grafting reaction that utilizes bacteria capture, contact-killing, inactivation activities achieve enhanced bactericidal biofilm elimination capabilities. Besides, mechanism between LG CS ascorbic acid (AA)/H2O2 redox system was further proposed. The LG-g-CS films feature side chains phenolic hydroxyl groups, facilitating dual capture contact-killing via strong electrostatic interactions with membranes as well blue light (BL)-driven eradication generation reactive oxygen species. As result, efficiently immobilize exhibit excellent activity against model (Escherichia coli Staphylococcus aureus) biofilms under BL irradiation. Moreover, could significantly promote healing process S. aureus-infected wounds. This research demonstrates new strategy designing fabricating sustainable biofilm-removing materials high activity.
