Affinity Peptides With pH Sensitivity for the Enrichment of CD38+ Cells

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The selective enrichment of cell populations based on surface markers is critical for the advancement of gene and cell therapies. Current antibody‐based cell isolation methods, such as fluorescence‐ and magnetic‐activated cell sorting (FACS and MACS), offer high specificity but are limited by scalability, cost, and potential adverse effects on

Microfiltration (MF) and Ultrafiltration (UF) for Sewage and Surface Water Concentration for SARS‐CoV‐2 and Other Enveloped Viruses' Detection in Wastewater‐Based Epidemiology (WBE)

Biotechnology and Bioengineering, EarlyView.
ABSTRACT This study objective was to evaluate hollow fiber membranes for concentration of enveloped enteric viruses in sewage and surface water samples. Microfiltration (MF, 0.2 µm nominal pore size) and ultrafiltration (UF, 100 kDa molecular weight cut‐off) hollow fiber membranes were compared for the concentration of the bovine respiratory syncytial ...

Homologous membrane wrapped ZIF‐8 nanoparticles accelerate differentiation of neural stem cell for spinal cord injury therapy

BMEMat, EarlyView.
Homologous membrane wrapped ZIF‐8 nanoparticles were proposed to improve biocompatibility and targeting ability to neural stem cells (NSCs). ZIF‐8‐SCM NPs exhibit pH responsiveness, thereby generating an intracellular Zn2+ storm to accelerate neural differentiation through calcium and MAPK signaling pathways. Moreover, they promote function recovery in

Near‐infrared light‐activated aptamer‐based nanoprobe for spatiotemporally resolved detection of L‐lactate in colorectal cancer

BMEMat, EarlyView.
A near‐infrared (NIR) light‐activated “lock‐key” nanodevice is reported for spatiotemporally resolved detection of intratumoral L‐lactate. The system stays silent until deep‐penetrating NIR light remotely unlocks its function, allowing for precise sensing within tumors.
