Laser-Induced Graphene Arrays-Based Three-Phase Interface Enzyme Electrode for Reliable Bioassays

Man Zhang et al.

Summary: Researchers constructed a three-phase interface enzyme electrode by immobilizing H2O2 electrocatalysts and an oxidase layer on a superhydrophobic laser-induced graphene (LIG) array substrate. The LIG-based enzyme electrode enhanced oxidase kinetics by providing constant and sufficient oxygen from the air phase to the enzymatic reaction zone. Compared to a solid-liquid diphase system, the enzymatic reaction rate was improved by 21.2-fold and the linear detection range was increased by 60 times. The three-phase enzyme electrode also minimized interferences and increased detection selectivity for H2O2 detection.

Molecularly imprinted polymer dual electrochemical sensor for the one-step determination of albuminuria to creatinine ratio (ACR)

Nur Indah Wardani et al.

Summary: An electrochemical sensor based on dual screen-printed carbon electrode was developed for quantification of urinary albumin to creatinine ratio (ACR), which is a convenient and accurate biomarker of chronic kidney disease (CKD). The sensor utilized modified working electrodes with carboxylated multiwalled carbon nanotubes and redox probes for creatinine and albumin. Molecularly imprinted polymer layers were used for selective recognition of creatinine and albumin, enabling simultaneous measurement through square wave voltammetry. The sensor demonstrated good linearity and sensitivity for both analytes, and showed stability and comparability with traditional methods.

Differential Amperometric Microneedle Biosensor for Wearable Levodopa Monitoring of Parkinson's Disease

Lu Fang et al.

Summary: L-Dopa is an effective therapy for Parkinson's disease, but its short half-life and narrow therapeutic window may lead to side effects. Monitoring the concentration of L-Dopa using wearable biosensors is significant to reduce complications. However, the high concentration of interferents in the body poses challenges. A minimal-invasive L-Dopa biosensor based on a flexible differential microneedle array (FDMA) is proposed to address this. The sensor exhibits excellent anti-interference performance and accuracy.

A Study on the Combination of Enzyme Stabilizers and Low Temperatures in the Long-Term Storage of Glutamate Biosensor

Andrea Bacciu et al.

Summary: This study analyzed the impact of glycerol and triethylene glycol as enzyme stabilizers, combined with long-term storage at low temperatures, on biosensor performance. The results showed that both glycols were capable of increasing enzymatic activity and maintaining good biosensor efficiency over time. Glycerol was more effective in stabilizing the enzyme and maintaining analytical performance when the biosensors were stored at -20 degrees C, while triethylene glycol performed the same function at -80 degrees C.

Accelerating AUTODOCK4 with GPUs and Gradient-Based Local Search

Diogo Santos-Martins et al.

Summary: AUTODOCK4 is a widely used program for docking small molecules to macromolecular targets, but its long execution times limit its applicability to large scale dockings. To address this issue, an OpenCL implementation called AUTODOCK-GPU has been developed, leveraging GPU hardware to significantly reduce docking runtime by up to 350-fold.

Natural Chain-Breaking Antioxidants and Their Synthetic Analogs as Modulators of Oxidative Stress

Vessela D. Kancheva et al.

Summary: Oxidative stress is caused by an increase in reactive oxygen species or a significant decrease in the effectiveness of antioxidant enzymes and nonenzymatic defense. A study compared the chain-breaking antioxidant activity of 40 phenolic antioxidants to investigate their role as modulators of oxidative stress. The research focused on the chemical reactions initiating free radicals and the effects of substituents in the phenolic structure.

Oxygen inhibition of free-radical polymerization is the dominant mechanism behind the mold effect on hydrogels

Rok Simic et al.

Summary: In this study, it was demonstrated that some molding materials release oxygen during polymerization, inhibiting free-radical polymerization near the interface. Removal of oxygen from the system resulted in homogeneously cross-linked hydrogel surfaces, allowing for the controlled adjustment of surface structures and mechanical properties through the regulation of oxygen levels.
