ABSTRACT Protein purification is essential for biomedical and industrial applications, but current methods often face challenges like low efficiency, high cost, limited selectivity. To overcome these drawbacks, we developed electrospun polyacrylonitrile (PAN) membranes with chitosan (Cs) evaluated their ability to capture bovine serum albumin (BSA) immunoglobulin G (IgG) from aqueous solutions. Comparing PAN/Cs pristine PAN membranes, showed Cs significantly enhances BSA adsorption. The were characterized using scanning electron microscopy, Fourier Transform Infrared Spectroscopy, tensile testing, surface area analysis, energy‐dispersive X‐ray spectroscopy, contact angle measurements. exhibited smooth, uniform fibers averaging 0.454 μm in diameter. maximum adsorption capacity () was 75.61 mg g −1 21.17 PAN, while IgG, 28.83 19.77 PAN. SDS‐PAGE electrophoresis confirmed that the eluted proteins maintained quality integrity. Elution efficiency of reached 89.13% 62.16% IgG. Additionally, selectively captured IgG when co‐dissolved These results position as promising materials efficient, cost‐effective, selective protein purification, potential applications both fields.

Efficient delivery of nanoparticles (NPs) as carriers for biochemical substances is crucial in various biomedical applications. In this study, we systematically investigate the interactions between glycosylated and nonglycosylated forms Apolipoprotein D (ApoD) with gold (AuNPs) functionalized different polymer coatings, including polyethylene glycol (PEG) zwitterionic polymers. Using all-atom molecular dynamics simulations, demonstrate that glycosylation significantly enhances adsorption behavior ApoD on AuNP surfaces, extent enhancement being dependent type (especially charge property) coatings. Notably, while polymers exhibit strong resistance to protein their form, antifouling capability diminished when present. Further, our findings reveal not only strengthens binding energy proteins but also alters hydration at NP–protein interface. Overall, study provides a deeper understanding role modulating protein–nanoparticle interactions, which essential design more effective nanomaterials precision medicine.

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.

While gold nanoparticles (AuNPs) should allow the delivery of surface immobilized drugs to intended target tissues via bloodstream, their interactions with plasma proteins may induce aggregation and thus impede an effective chemotherapeutic agents tissues. The deliberate treatment AuNPs has potential overcome this inherent limitation. To probe between treated in blood plasma, we employed a size-exclusion chromatography (SEC)-based metallomics tool together transmission electron microscopy (TEM). After addition citrate capped its analysis revealed >670 kDa Au species, which TEM identified as AuNP-plasma protein aggregates. ameliorate formation latter, was modified dithiothreitol (DTT), meso 2,3-dimercaptosuccinic acid (DMSA), or 2,3 dimercapto-1-propionesulfonic (DMPS) effect probed after these rabbit plasma. results for DMSA/DMPS-treated that tight binding dithiols more significantly reduced corona compared DTT-AuNPs implying DMSA DMPS is feasible strategy control AuNP-based using targeting sequences cancer can be enhanced by DMPS. Since left over AuNP mobilized iron from metalloproteins, excess must removed before injecting patients.
