Dynamic Profiling of Lipoteichoic Acid (LTA) and/or Lipopolysaccharide (LPS) Positive Extracellular Vesicles in Plasma as Diagnostic and Prognostic Biomarkers for Bacterial Infection

Advanced Science
Bacterial extracellular vesicles (EVs) are emerging as promising biomarkers for diagnosing bacterial infections. This study explores the diagnostic potential of plasma EVs carrying bacterial lipopolysaccharide (LPS) or lipoteichoic acid (LTA).

A Naphthalimide‐Based NIR‐Emissive AIE Photosensitizer for Synergistic Apoptosis/Ferroptosis‐Mediated Antitumor Therapy and Broad‐Spectrum Bacterial Inactivation With Rapid Wound Healing

Advanced Healthcare Materials, EarlyView.
An ionic naphthalimide AIE photosensitizer (PS), TPAPV‐NIM‐M, anchors to cellular and bacterial membranes, emits in the far‐red/near‐infrared (NIR) region, and efficiently generates reactive oxygen species (ROS) under white light. Its membrane‐localized photodynamic action drives apoptosis/ferroptosis‐mediated tumor suppression and broad‐spectrum ...

Identification of protein biomarkers to differentiate between gram-negative and gram-positive infections in adults suspected of sepsis

BMC Infectious Diseases
Background Sepsis is mostly caused by bacterial infections and requires a prompt diagnosis. There is a need for improved diagnostics by differentiating between gram-negative and gram-positive bacterial infections.

Nanomaterial Strategies for Pulmonary Delivery of Immunotherapeutics in Lung Cancer Treatment

Advanced Healthcare Materials, EarlyView.
Inhalable immunotherapeutic nanomedicines enable organ‐selective immune modulation by overcoming pulmonary delivery barriers and concentrating therapy within lung tumors. This Review defines how nanomaterial properties govern airway deposition, retention, cellular partitioning, and immune activation across vaccines, checkpoint blockade, STING agonists,

Rare‐Earth–Functionalized Carbon Dot Hydrogels as Mechanically Robust Antibacterial Wound Dressings

Advanced Healthcare Materials, EarlyView.
The schematic depicts a dynamically cross‐linked PVA hydrogel network in which reversible borate ester bonds and hydrogen‐bonding interactions integrate lanthanum‐doped carbon dots (La‐CDs) and dipotassium glycyrrhizinate (DPG) to form a mechanically robust, multifunctional matrix.

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.
