Electrochemical sensors exhibit distinct advantages over alternative sensor modalities in the swift detection of microorganisms. In this study, we devised a label-free electrochemical immunosensor utilizing CoFe-MOFs@MWCNTs composite-modified electrodes for specific Salmonella milk. The integration composites onto electrode surface effectively enhanced current response and furnished an abundance active sites, subsequently augmented by electrodeposited AuNPs signal amplification antibody conjugation. microstructural characteristics composite were meticulously examined via scanning electron microscopy, while its elemental composition chemical structure thoroughly analyzed using energy-dispersive X-ray spectroscopy Fourier transform infrared spectroscopy, respectively. Upon optimization experimental parameters, demonstrated exceptional sensitivity, specificity, stability, exhibiting linear range spanning from 1.04×104 to 1.04×108 CFU mL-1 Salmonella, with limit (LOD) 2.89 × 103 mL-1. This innovative holds promise cow's milk presents novel approach monitoring foodborne pathogens.

It is crucial yet challenging to sensitively quantify low-abundance biomarkers in blood for early screening and diagnosis of various diseases. Herein, an analytical model intra-mesopore immunoassay (IMIA) was proposed, which competent examine at the femtomolar level. The success rooted design innovative superparamagnetic core-shell structure with Fe3O4 nanoparticles (NPs) core hierarchically porous zeolitic imidazolate frameworks as a shell (Fe3O4@HPZIF-8), achieved through soft-template directed self-assembly coupled confinement growth mechanism. Such unique configuration conceptualized IMIA where HPZIF-8 served solid carrier cover capture antibodies while assisted its rapid separation. large pore channels not only provided stable microenvironment maintain recognition ability captured but also enhanced their coating density, thus promoting probability capturing binding target antigens, significantly improving (IA) sensitivity. practical clinic IA cTnI (Cardiac Troponin I, biomarker acute myocardial infarction (AMI)) human serums exemplified. developed could accurately slight fluctuations concentrations AMI patients different stages after symptom onset more than 100-fold enhancement limit detection (LOD) comparison conventional plate-based enzyme-linked immunosorbent assay (ELISA). high sensitivity makes it powerful tool accurate diseases by altering type primary antibody.

Wound care always presents challenges as they are susceptible to bacterial infections and have mechanical compatibility issues with wound dressings, leading a delayed recovery of the structure functional integrity skin tissue. Herein, an iron-based metal-organic framework loaded gold (Fe-MIL-88NH2-Au) nanozyme based composite hydrogel (HMAux) excellent dual-mode antibacterial properties was designed for care. To obtain HMAux, Fe-MIL-88NH2-Au photothermal peroxidase-like oxidase-like activities prepared. Then it introduced into system sea-island which prepared via copolymerization acrylamide acryloyl Pluronic F127 (PF127-DA) in aqueous solution. Using dynamic micelles energy dissipation mechanism, double bonds intermolecular interactions two crosslinking methods HMAux make possess good stretchability (3244 %-4524 %), toughness (593.8 kJ/m3 421.5 kJ/m3), low hysteresis (0.13-0.15). Furthermore, synergistic chemodynamic effects provide performance under mild conditions, killing rates approximately 95.02 % 97.28 S. aureus E. coli, respectively. In vivo experiments proved that can effectively adapt contour treat infections.
