Gold Single‐Atom Catalysts Enable Selective Shuttle Hydrochlorination of Alkynes

Angewandte Chemie International Edition, EarlyView.
Gold single‐atom catalysts on activated carbon enable heterogeneous shuttle hydrochlorination of terminal alkynes to vinyl chlorides with high chemo‐ and stereo‐selectivity thanks to cooperation between Au(I) sites and the support. The catalytic system combines broad substrate compatibility, simplified separation, and recoverability, paving the way for

Host Cell Protein Challenges in Antibody Processing: Insights Into Persistence and Mitigation Strategies

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Persistence of HCPs remains a major purification challenge in biopharmaceutical manufacturing with direct consequences for product quality, patient safety, and regulatory compliance. Over the last two decades, deeper insights into the mechanisms driving HCP persistence have clarified why certain proteins evade removal during purification ...

Serotype‐Tailored Midstream and Downstream Operations to Advance the Manufacturing of Adeno‐Associated Viral Vectors

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Adeno‐associated viruses (AAVs) are the leading vectors for in vivo gene therapy, fueling a growing demand for scalable and robust biomanufacturing processes. Yet, the impact of cell lysis conditions on the performance of midstream and downstream unit operations across serotypes remains poorly characterized.

Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms

BMEMat, EarlyView.
This review highlights critical “translational gaps” in understanding micro‐ and nanoplastics impacts on gastrointestinal diseases, bridging exposure, detecting, and mechanistic toxicology. Abstract Micro‐ and nanoplastics (MNPs) have become pervasive environmental contaminants with increasing evidence linking them to adverse health outcomes.

Electron compensation‐gated nanomotor for immunomodulation and microenvironment remodeling in bacterial pneumonia therapy

BMEMat, EarlyView.
A nanomotor featuring an “electronic lock” via electron compensation in an Au‐Ag alloy ensures therapeutic precision. Near‐infrared light acts as a key, unlocking on‐demand Ag+ release for synergistic bactericidal action and microenvironment remodeling to potently treat bacterial pneumonia. Abstract Bacterial pneumonia treatment is severely hampered by

Defect‐engineered tungsten oxide nanowires as redox‐metabolic nanozymes for gut inflammation‐infection syndromes

BMEMat, EarlyView.
Defect‐engineered WO3 nanowires serve as a multifunctional nanozyme platform to treat IBD complicated by Salmonella co‐infection. By integrating catalytic ROS/RNS scavenging and targeted metabolic interference of pathogens via molybdenum substitution, these nanowires effectively resolve intestinal oxidative stress, inhibit infection, and restore ...
