Bilateral SERS‐Microneedle Patch for Co‐Diagnosis of Diabetes Mellitus and Tuberculosis Comorbidity

open access: yesAdvanced Science, EarlyView.
Our study introduced a U@mP@Au‐mediated bilateral SERS‐microneedle patch for analyzing glucose levels from ISF and sensitively detecting TB biomarkers from sputum, respectively. This integrated dual‐analyte detecting platform can be used for co‐diagnosis of diabetes mellitus (DM) and tuberculosis (TB) comorbidity, which was demonstrated in ex vivo ...

Structural Studies of Catalysis and Processing in Galactose [PDF]

open access: yes, 2007
The fungal copper containing enzyme galactose oxidase is one of the earliest examples of a protein derived radical cofactor. A covalent bond, formed between the active site cysteine and the Cc of a tyrosine act as a site for radical formation, allowing ...

Effect of glucose oxidase to catalase ratio in biomaterial.

open access: yes, 2016
(A) Hydrogen peroxide concentration after 24 hours incubation. The ratio of glucose oxidase to catalase was adjusted to 1:0, 1:1, 1:5, 1:10 and 1:50. (B) D-glucose concentration after 4, 12, 24 and 48 hours incubation. Glucose oxidase coating density was

A Sprayable Nanoplatform Breaks the Vicious Cycle of Diabetic Wounds via Photoactivated Antioxidant and Drug Delivery

open access: yesAdvanced Science, EarlyView.
A sprayable near‐infrared‐activated nanoplatform incorporating MXene, ZnHCF nanozyme, and deferoxamine efficiently breaks the vicious cycle of diabetic wounds. Upon irradiation, interfacial electron transfer and photothermal effects enhance multi‐enzyme activity, enabling explosive ROS elimination, alleviation of hypoxia, and controlled DFO release ...

Robust Amorphous MOF‐Based Aerogels Digital Biosensor for Sensitive Detection of Organophosphate Pesticides

open access: yesAdvanced Science, EarlyView.
We report a robust aerogel digital biosensor by integrating an enzyme‐mediated amorphous MOF within an aerogel matrix for on‐site pesticide detection. The enzyme‐mediated assembly strategy enables in situ tailoring of MOF into a porous amorphous structure, achieving both high stability and activity.

Mechanistic Understanding of Protein–MOF Integration Through Surfactant‐Driven Interfacial Design

open access: yesAdvanced Science, EarlyView.
This study reveals how surfactant‐driven interfacial design governs the assembly and stability of protein@MOF composites. Using lipid‐based nonionic surfactants, we modulate protein–MOF interactions to improve encapsulation efficiency, MOF crystallization, and catalytic performance.
