Bacteria can cause infectious diseases even at ultralow concentrations (<1 CFU/mL). It is important to rapidly identify bacterial contamination concentrations. Herein, FITC-labeled gelatinase-sensitive nanoparticles (GNPs@FITCs) and NFM@GNP@FITCs are designed fabricated as concentration bacteria detection platforms based on an enzymatic cascade reaction-amplifying strategy. Bacterial secretions could trigger the dissociation of GNPs@FITCs release FITC, with gelatinase used model secretion. The detectable signal be amplified effectively by gelatinase-triggered reaction. was evaluated change in fluorescence density. results showed that for identifying qualitatively, when lower than 1 CFU/mL. Moreover, method has better timeliness convenience, compared national standards. As solid films, have long-term storage stability GNPs@FITCs. potential applications GNPs@FITC were proved detecting pathogenic food. All great screening qualitatively.

The healing of biofilm-infected diabetic wounds characterized by a deteriorative tissue microenvironment represents substantial clinical challenge. Current treatments remain unsatisfactory due to the limited antibiofilm efficacy caused weak and biofilm permeability drugs risk reinfection during process. To address these issues, an integrated therapeutic preventive nanozyme-based microneedle (denoted as Fe2 C/GOx@MNs) is engineered. dissolvable tips with enough mechanical strength can deliver rapidly release C nanoparticles (NPs)/glucose oxidase (GOx) in active regions, enhancing NPs/GOx, ultimately achieving highly efficient elimination. Meanwhile, chitosan backing layer not only act excellent physical barrier between wound bed external environment, but also prevent bacterial reinvasion its superior antibacterial property. Significantly, elimination prevention abilities C/GOx@MNs on are proved methicillin-resistant Staphylococcus aureus-biofilm-infected mouse model full-thickness wound. Together, results demonstrate promising application healing.
