Food-borne illnesses are a growing concern for the food industry and consumers, with millions of cases reported every year. Consequently, there is critical need to develop rapid, sensitive, inexpensive techniques pathogen detection in order mitigate this problem. However, current strategies mainly include time-consuming laboratory methods highly trained personnel. Electrochemical in-field biosensors offer low-cost alternative techniques, but electrodes used these require expensive...
The integration of microfluidics and electrochemical cells is at the forefront emerging sensors energy systems; however, a fabrication scheme that can create both in scalable fashion still lacking. We present one-step, mask-free process to create, pattern, tune laser-induced graphene (LIG) with ubiquitous CO2 laser. laser parameters are adjusted LIG different electrical conductivity, surface morphology, wettability without need for postchemical modification. Such definitive control over...
Visual pH-sensing cellulose acetate (CA)-based films was incorporated with different concentrations of red cabbage extract (RCE). The were characterized by color, barrier and thermal properties, microscopic topographic characteristics, mechanical performance, detection capacity volatile ammonia, time-dependent color stability lighting. RCE incorporation into CA-based promoted a color-changing an increased light exhibited plasticizer effect on the properties films. Moreover, surface patterns...
Abstract Extensive research into green technologies is driven by the worldwide push for eco‐friendly materials and energy solutions. The focus on synergies that prioritize sustainability environmental benefits. This study explores potential of abundant, non‐toxic, sustainable resources such as paper, lignin‐enriched cork producing laser‐induced graphene (LIG) supercapacitor electrodes with improved capacitance. A single‐step methodology using a CO 2 laser system developed fabricating these...
Saliva-based sensors are becoming increasingly important in medical diagnostics and sports medicine due to the plethora of biomedically relevant analytes found endogenously within fluid inherently noninvasive nature sensing protocols. Salivary lactate potassium have been shown be key indicators for monitoring fatigue, hydration, overall health, frequent is crucial preventative treatment strategies. Low-cost test strip combined with saliva swab sampling could enable such monitoring, this end,...
Currently, improvement of food preservation has been a substantial challenge for industries to increase shelf-life products and maintain quality during storage. These goals are often tied the sustainable tendency use eco-friendly packaging store these without loss features. Therefore, aim this study was produce biodegradable antimicrobial films by incorporation nisin Z peptide under different concentrations (0 %, 5 10 15 % 20 wt.) into hydroxypropylmethylcellulose (HPMC) matrices. The active...
Abstract: The objective of this work was to develop gluten-free cookies and savory fried pies using tannin-rich sorghum (Sorghum bicolor) flour, evaluate their in vitro starch digestibility, verify how knowledge benefits may contribute the sensory acceptability both products. contents rapidly digestible starch, slowly resistant were determined. Sensory acceptance evaluated two sessions: one without information on human health; another where presented. (5.07 16.22%, respectively) about twice...
Flexible carbon nanomaterial sensors offer a low-cost, facile fabrication approach toward producing at an industrial scale for electrochemical sensing. Graphene and nanotube (CNT) based have been studied, with various methods available, including high-quality thin film graphene CNTs via chemical vapor deposition (CVD). However, CVD is high-temperature vacuum process that low-yielding consequently costly, hindering its implementation into single-use test strip sensors. Other methods, such as...
Carbon-nanomaterial sensors offer promising routes toward low-cost, high-throughput electrochemical sensors. Carbon nanomaterials, such as graphene and carbon nanotube (CNT), have been studied with various fabrication methods to produce sensors, including high-quality thin film CNT by chemical vapor deposition. However, the complexity cost associated their hindered implementation into single-use test strip Even high-yield mechanical and/or exfoliation of from graphite followed solution phase...
