The formation of a protein corona (PC) can significantly impact the detection ability gold nanoparticles (AuNPs)-small molecule adsorbent probes based on competitive adsorption. To alleviate this problem, in study, double-stranded DNA (dsDNA) was introduced to modify AuNP mitigate negative effect PCs small molecules by taking AuNPs-dichlorofluorescein (DCF) probe-based ambroxol hydrochloride (AMB) as study model. It found that dsDNA-modified AuNPs-DCF probe (dsDNA@AuNPs-DCF), accuracy for AMB improved, which might be attributed isolation proteins from surface AuNPs while still allowing access due introduction rigid dsDNA. Further, strand length and number dsDNA modified antifouling performance then investigated, it LOD value artificial milk samples dsDNA10bp90@AuNPs-DCF (with 10 base 90:1 ratio AuNPs) is decreased more than 2-fold compared with probe. Moreover, probes, recovery rates analyzed commercial greatly improved probe, particularly when contained much lower concentrations. This demonstrates dsDNA-based antiprotein corona-fouling strategy AuNPs-small provides beneficial ideas dealing interference resulting studying biological samples.

Chemical gradients are essential in biological systems, affecting processes like microbial activity soils and nutrient cycling. Traditional tools, such as microsensors, offer high-resolution data but limited to one-dimensional measurements. Planar optodes allow for two-dimensional (2D) three-dimensional (3D) chemical imaging often sensitive temperature changes. This study presents an advanced dual-emission optical sensor that simultaneously measures oxygen using a modified platinum(II) meso-tetrakis(3,5-di

Optode-based chemical imaging is a rapidly evolving field that has substantially enhanced our understanding of the role microenvironments and gradients in biogeochemistry, microbial ecology, biomedical sciences. Progress sensor chemistry resulted broadened spectrum analytes, alongside enhancements performance (e.g., sensitivity, brightness, photostability). However, existing techniques are often costly, challenging to implement, limited their recording speed. Here we use "frame-straddling" technique, originally developed for particle image velocimetry O
