Carbon dioxide (CO2) gas sensing and monitoring have gained prominence for applications such as smart food packaging, environmental of greenhouse gases, medical diagnostic tests. Although CO2 sensors based on metal oxide semiconductors are readily available, they often suffer from limitations high operating temperatures (>250 °C), limited response at elevated humidity levels (>60% RH), bulkiness, selectivity. In this study, we designed a chemiresistive sensor detection to overcome these...
Abstract Glucose plays critical roles in many human body functions, above all as a source of energy. Abnormal levels glucose are correlated to different diseases, importantly including diabetes. As such, quantification fluids is essential for health monitoring. Blood tests and, more recently, portable interstitial fluid tests, currently represent the benchmarks detection. Inconvenient invasive methods such blood pose burdens on both patients and healthcare system. In this review, noninvasive...
Abstract Detecting hydrogen peroxide (H 2 O ) as the side product of enzymatic reactions is great interest in food and medical applications. Despite advances this field, majority reported H sensors are bulky, expensive, limited to only one phase detection (either gas or liquid), require multistep fabrications. This article aims address some these limitations by presenting a 3D printable paper‐based sensor made from poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) decorated...
Highlights•Material anisotropy and toughness are crucial for polymeric heart valve development•Structural reinforcement enhances both properties while retaining function•The resistance of a polyurethane to fracture increased 9-fold after reinforcement•This strategy improved closure maintaining opening behaviorSummaryValvular diseases commonly addressed by the implantation replacement devices; however, current prosthetics remain suboptimal in their performance longevity, often necessitating...
The concentration of nonesterified fatty acids (NEFAs) in biological media is associated with metabolic and cardiovascular disorders (e.g., diabetes, cancer, cystic fibrosis) food products indicative their quality. Therefore, the early identification NEFAs crucial for both medical diagnosis quality assessment. However, development a portable scalable sensor capable detecting these compounds at low cost presents challenges due to considerable chemical physical stability. This research...
Abstract Traditional organic‐based chemiresistive sensors have been a key area of research due to their portability, low power consumption, cost, turnability, and possibility for miniaturization. However, real‐world applications remained restricted by selectivity, sensitivity, stability under demanding conditions, such as extreme temperature, humidity, pH. As such, this review aims lay the foundation enhancing performance these gas via chemical physical modifications. To end, an insight into...

In this study, a bioinspired valve was designed, assessed silico, validated by an vitro model to develop with optimum function for pediatric applications.A created computationally leaflet curvature derived from native anatomies. A diameter 18 mm chosen approach sizes suitable younger patients. Valves different thicknesses were fabricated via dip-coating siloxane-based...
Sensitive, rapid, and continuous detection of hydrogen peroxide (H 2 O ) is great importance in complex systems for quality control, healthcare products, medical diagnostics, food safety, environmental protection. Yet, the monitoring H remains challenging due to cost, lack specificity, bulkiness current sensor technologies. These challenges are exacerbated applications where must be fully submerged a liquid media. In this work, highly flexible hydrogel-based electrochemical constructed...
