Thread-Based Bienzymatic Biosensor for Linoleic Acid Detection.

The concentration of nonesterified fatty acids (NEFAs) in biological media is associated with metabolic and cardiovascular disorders (e.g., diabetes, cancer, and cystic fibrosis) and in food products is indicative of their quality.

Chemiresistive Sensor for Enhanced CO Gas Monitoring.

Carbon dioxide (CO) gas sensing and monitoring have gained prominence for applications such as smart food packaging, environmental monitoring of greenhouse gases, and medical diagnostic tests. Although CO sensors based on metal oxide semiconductors are readily available, they often suffer from limitations such as high operating temperatures (>250 °C), limited response at elevated humidity levels (>60% RH), bulkiness, and limited selectivity. In this study, we designed a chemiresistive sensor for CO detection to overcome these problems.

Bioinspired polymeric heart valves: A combined in vitro and in silico approach.

Background: Polymeric heart valves (PHVs) may address the limitations of mechanical and tissue valves in the treatment of valvular heart disease. In this study, a bioinspired valve was designed, assessed in silico, and validated by an in vitro model to develop a valve with optimum function for pediatric applications.

Methods: A bioinspired heart valve was created computationally with leaflet curvature derived from native valve anatomies.

Flexible Sensors for Hydrogen Peroxide Detection: A Critical Review.

Hydrogen peroxide (HO) is a common chemical used in many industries and can be found in various biological environments, water, and air. Yet, HO in a certain range of concentrations can be hazardous and toxic. Therefore, it is crucial to determine its concentration at different conditions for safety and diagnostic purposes.
