Ionic liquid-carbon composite glucose biosensor

Biosensors and Bioelectronics, 2008
The use of ionic liquids that are solid at room temperature such as n-octyl-pyridinium hexafluorophosphate (nOPPF(6)) is shown to be advantageous in the fabrication of new form of biocomposite materials with attractive performance over other types of composites and pastes involving non-conductive binders.

Stiff to Soft: A Protein‐Based Buffer Layer for Improving the Long‐Term Performance of Microneedle Sensors

Advanced Materials, EarlyView.
To enhance stability and long‐term biocompatibility of wearable microneedle sensors, a crosslinking‐recombination bovine serum albumin material is used as a buffer layer coated on microneedle sensors. This coating layer possesses a unique stiff‐to‐soft transition function balancing the mechanical stiffness desired for puncturing and soft required for ...

Glucose Determination by Biosensors

Biochemistry & Analytical Biochemistry, 2012
Sugars constitute a class of biocomponents, which can reach in plants an amount of almost 50% of their dried weight. Glucose, fructose and saccharose are found in significant amounts in fruits and honey. Glucose or dextrose occurs naturally in fruits and vegetables as the primary product of photosynthesis.

Engineering Active Metal Oxide Interfaces on MOF‐Derived 3D Carbon Architecture for Small‐Molecule Biosensing

Advanced Materials Interfaces, EarlyView.
MOFs awaken graphene. MOF‐assisted ultrafast laser writing patterns porous laser‐induced graphene with CuO‐active nanodomains, creating an aptamer‐ready interface for small‐molecule capture. Coupled to an extended‐gate FET, the hybrid converts subtle biochemical binding into a clear electrical signal for resilient cortisol sensing in aqueous media ...
