Ultrafiltration Membranes for Microdialysis

Hungarian Journal of Industry and Chemistry
Porous asymmetric polysulfone ultrafiltration membranes were prepared via the nonsolvent-induced phase separation process. The composition of the casting solution was optimized to achieve the required transport properties before membranes in the form of hollow fibers were prepared and characterized.

Enhancing antifouling property of polysulfone ultrafiltration membrane by grafting zwitterionic copolymer via UV-initiated polymerization

, 2009
A new kind of zwitterionic molecule, [3-(methacryloylamino)propyl]-dimethyl (3-sulfopropyl) ammonium hydroxide inner salt (MPDSAH) was grafted onto polysulfone (PSF) ultrafiltration membrane surface using benzophenone (BP) as the initiator to improve the

Organic Nanozyme‐Embedded Biotherapeutic Thermosensitive Hydrogel for Extracellular GSH Depletion and Postoperative Tumor Suppression

Advanced Science, EarlyView.
A temperature‐sensitive hydrogel loaded with cyanine nanozymes and Escherichia coli is locally injected into postoperative tumor resection beds. Upon light irradiation, synergistic PTT and PDT work with cascaded reactive oxygen species to deplete extracellular GSH, eliminate residual tumor cells, and induce robust antitumor immune responses for ...

Targeting the NR1D1–IGF2BP2–V‐ATPase Axis With Hybrid Nanovesicles Restores Macrophage Rhythms to Reverse Sepsis‐Induced Immunosuppression

Advanced Science, EarlyView.
Sepsis disrupts immune‐cell rhythms and weakens bacterial clearance. Biomimetic nanovesicles combining erythrocyte and inflammation‐activated macrophage membranes deliver siNR1D1 to dysfunctional macrophages, restoring the NR1D1–IGF2BP2–V‐ATPase pathway, circadian regulation, phagolysosomal acidification, and antimicrobial defense.

A Photothermally Amplified Enzyme–Nitric Oxide Co‐Regulatory System Reprograms Pathological ECM–Fibroblast Crosstalk to Alleviate Hypertrophic Scarring

Advanced Science, EarlyView.
An enzyme–nitric oxide (NO) co‐regulatory strategy reprograms pathological extracellular matrix (ECM)–fibroblast crosstalk in hypertrophic scars. Enzymatic degradation of pre‐existing ECM relieves aberrant mechanical cues, while NO‐mediated fibroblast phenotypic modulation restrains excessive collagen synthesis.

The Effect of Ligand Reactivity and Carrier Mechanics on Thiol‐Mediated Cellular Uptake for miRNA Nano‐Drugs

Advanced Science, EarlyView.
The effect of ligand reactivity and carrier mechanics on thiol‐mediated uptake was investigated at the single‐molecule/particle level. The interaction kinetics of LA and AspA with membrane thiols were quantified; AspA is more efficient due to the higher binding affinity, greater binding stability, and more double‐disulfide binding, as well as greater ...

Extraction of amaranth starch from an aqueous medium using microfiltration [PDF]

, 2011
Amaranth starch granules are very small, which makes them suitable for a range of specialty applications. This starch is difficult to extract by wet milling due to the strong association between the starch and protein, the high protein content of the ...

A Dual‐Mode In Situ EV‐miRNA Profiling Platform for Machine‐Learning‐Assisted Gastric Cancer Liquid Biopsy

Advanced Science, EarlyView.
An in situ dual‐mode platform integrates fusogenic liposomes with localized autocatalytic DNA circuits for plasma‐derived extracellular vesicle microRNA analysis. Following membrane fusion, target miRNAs trigger feedback‐assisted LECHA amplification inside intact vesicles, generating fluorescence and electrochemical outputs. Machine learning integrates
