Core-Shell Magnetic Particles: Tailored Synthesis and Applications.

Core-shell magnetic particles consisting of magnetic core and functional shells have aroused widespread attention in multidisciplinary fields spanning chemistry, materials science, physics, biomedicine, and bioengineering due to their distinctive magnetic properties, tunable interface features, and elaborately designed compositions. In recent decades, various surface engineering strategies have been developed to endow them desired properties (e.g.

Subclinical disease among people with culture-confirmed pulmonary tuberculosis in Singapore - a retrospective study.

Introduction: Subclinical tuberculosis (TB) is challenging to diagnose due to the lack of a clear definition and symptoms. This study aimed to describe the subclinical disease spectrum among people with culture confirmed pulmonary tuberculosis routinely diagnosed in Singapore, a country with moderate incidence, utilising different definitions. It also aimed to identify risk factors for subclinical TB and the current diagnostic approaches in detecting subclinical TB.

Gene editing tool-loaded biomimetic cationic vesicles with highly efficient bacterial internalization for in vivo eradication of pathogens.

In the post-COVID-19 era, drug-resistant bacterial infections emerge as one of major death causes, where multidrug-resistant Acinetobacter baumannii (MRAB) and drug-resistant Pseudomonas aeruginosa (DRPA) represent primary pathogens. However, the classical antibiotic strategy currently faces the bottleneck of drug resistance. We develop an antimicrobial strategy that applies the selective delivery of CRISPR/Cas9 plasmids to pathogens with biomimetic cationic hybrid vesicles (BCVs), irrelevant to bacterial drug resistance.

A Neuronal Signal Sorting and Amplifying Nanosensor for EEG-Concordant Imaging-Guided Precision Epilepsy Ablation.

Surgery remains an essential treatment for managing drug-resistant focal epilepsy, but its accessibility and efficacy are limited in patients without distinct structural abnormalities on magnetic resonance imaging (MRI). Potassium ion (K), a critical marker for seizure-associated neuronal signaling, shows significant promise for designing sensors targeting hidden epileptic foci. However, existing sensors cannot cross the blood-brain barrier and lack the ability to specifically enrich and amplify K signals in the brain with high temporal and spatial resolution.
