Abstract Infectious diseases (such as wound infections) caused by pathogenic microorganisms can lead to serious consequences and even threaten life. The emergence of drug‐resistant bacteria has severely prevented the validity traditional antibiotics. Therefore, developing novel antimicrobial strategies without holds great promise for maximizing efficacy minimizing risk drug‐resistance resistant bacterial infections. Herein, near‐infrared (NIR)‐absorbing A–D–A type conjugated oligomers with a tunable backbone are designed synthesized regulating their photothermal conversion. After being assembled into nanoparticles, oligomer CP‐F8P nanoparticles (NPs) containing strong electron‐donating component show strongest conversion efficiency 81.6%. low concentration NPs receive over 99% against Amp r E. coli , S. aureus C. albicans upon NIR irradiation, phototherapy treatment effectively promote healing in diabetic mice good biocompatibility.

Currently, there are no clinical drugs available to treat acute kidney injury (AKI). Given the high prevalence and mortality rate of AKI, development effectively AKI is a huge unmet medical need research hotspot. Although existing evidence fully demonstrates that reactive oxygen nitrogen species (RONS) burst at site major contributor progression, heterogeneity, complexity, unique physiological structure make most antioxidant anti-inflammatory small molecule ineffective because lack targeting side effects. Recently, nanodrugs with intrinsic through control size, shape, surface properties have opened exciting prospects for treatment AKI. Many emerged address limitations current treatments. In this review, we systematically summarized first time about emerging exploit pathological features overcome traditional small-molecule achieve efficacy. First, analyzed structural characteristics main mechanism AKI: hypoxia, harmful substance accumulation-induced RONS renal despite multifactorial initiation heterogeneity Subsequently, introduced strategies used improve reviewed advances nano-RONS-sacrificial agents, nanozymes, nanocarriers antioxidants drugs. These demonstrated excellent therapeutic effects, such as greatly reducing oxidative stress damage, restoring function, low Finally, discussed challenges future directions translating into treatment.

Abstract Due to the emergence of drug resistance in bacteria and biofilm protection, achieving a satisfactory therapeutic effect for bacteria‐infected open wounds with conventional measures is problematic. Here, photothermal cascade nano‐reactor (CPNC@GOx‐Fe 2+ ) constructed through supramolecular strategy hydrogen bonding coordination interactions between chitosan‐modified palladium nano‐cube (CPNC), glucose oxidase (GOx), ferrous iron (Fe ). CPNC@GOx‐Fe exhibits excellent effects powers GOx‐assisted reaction generate hydroxyl radicals, enabling chemodynamic combination therapy against biofilms. Further proteomics, metabolomics, all‐atom simulation results indicate that damage radical function structure cell membrane thermal enhance fluidity inhomogeneity bacterial membrane, resulting synergistic antibacterial effect. In biofilm‐associated tooth extraction wound model, generated from process can initiate polymerization form hydrogel situ protection. vivo experiments confirm protection accelerate healing infected tooth‐extraction without affecting oral commensal microbiota. This study provides way propose multifunctional system treatment infection.

Near-infrared-II (NIR-II, 1000-1700 nm) light-triggered photothermal therapy (PTT) has been regarded as a promising candidate for cancer treatment, but PTT alone often fails to achieve satisfactory curative outcomes. Hollow nanoplatforms prove be attractive in the biomedical field owing merits including good biocompatibility, intrinsic physical-chemical nature and unique hollow structures, etc. On one hand, themselves can NIR-II agents (PTAs), cavities of which are able carry diverse therapeutic units realize multi-modal therapies. other PTAs capable decorating on surface combine with functions components encapsulated inside synergistic treatment. Notably, generally serve photoacoustic imaging (PAI) contrast (CAs), means such kind also expected multifunctional all-in-one nanotheranostics. In this review, recent advances single-modal PTT, dual-modal PTT/photodynamic (PDT), PTT/chemotherapy, PTT/catalytic PTT/gas well PTT/chemodynamic (CDT)/chemotherapy, PTT/chemo/gene PTT/PDT/CDT/starvation (ST)/immunotherapy summarized first time.
