Gut microbiota plays an important role in host physiology such as obesity, diabetes, and various neurological diseases. Thus, microbiome sampling is a fundamental approach towards better understanding of possible However, conventional methods, endoscopies or colonoscopies, are invasive cannot reach the entire small intestine. To address this need, battery-less 3D-printed capsule, which can collect samples throughout entirety GI tract was designed. The capsule (9 mm × 15 mm) consists 3D...
Chronic nonhealing wounds are a growing socioeconomic problem that affects more than 6 million people annually solely in the United States. These colonized by bacteria often develop into biofilms act as physical and chemical barrier to therapeutics tissue oxygenation leading chronic inflammation hypoxia. Although wound debridement vigorous mechanical abrasion techniques used clinical professionals manage remove from surfaces, such methods highly nonselective painful. In this study, we have...
During the γ-radiation sterilization process, levels of radiation exposure to a medical device must be carefully monitored achieve required without causing deleterious effects on its intended physical and chemical properties. To address this issue, here we have demonstrated development an all-printed disposable low-cost sensor that exploits change in electrical impedance semi-interpenetrating polymer network (SIPN) composed poly(vinyl alcohol) (PVA)...
Laser-assisted surface alloying (LSA) process to modify orthopedic implant surfaces with Ti–Ag alloy for enhanced antibacterial and osteoinduction properties.
We are introducing a wireless and passive strain sensing scheme that utilizes ultrasound imaging of highly stretchable hydrogel embedded with zinc oxide (ZnO) nanoparticles, named "ZnO-gel". The incorporation ZnO nanoparticles into polymer network the improves both its elasticity strength. It also serves as an ideal biocompatible contrast agent allows remote interrogation changes in volume or dimensions response to mechanical strains through simple imaging. A systematic study various ratios...
Contamination of meat with pathogenic microorganisms can cause severe illnesses and food waste, which has significant negative impacts on both general health the economy. In many cases, expiration date is not a good indicator freshness as there high risk contamination during handling throughout supply chain. Many biomarkers, including color, odor, pH, temperature, volatile compounds, are used to determine spoilage. Among these, pH presents simple effective biomarker directly linked...
Many commercially available pH sensors are fabricated with a glass membrane as the sensing component because of several advantages glass-based electrodes such versatility, high accuracy, and excellent stability in various conditions. However, their bulkiness poor mechanical properties, conventional not ideal for wearable or flexible applications. Here, we report first time fabrication sensor suitable biomedical environmental applications where flexibility critical long-term real-time...
Wearable electronics have become integral for monitoring physiological parameters in diverse applications, particularly medical and military fields. e-Textiles, featuring integrated conductive threads or fabrics, offer seamless integration comfort prolonged contact with the body. Despite their potential, biofouling of textile-based electrode systems by skin microbes remains a significant challenge, limiting operational lifespan. Recent studies highlighted efficacy nanocomposites...
The problematic combination of a rising prevalence skin and soft tissue infections the growing rate life-threatening antibiotic resistant presents an urgent, unmet need for healthcare industry. These evolutionary resistances originate from mutations in bacterial cell walls which prevent effective diffusion antibiotics. Gram-negative bacteria are special consideration due to natural resistance many common antibiotics unique bilayer structure wall. system developed here provides one solution...
This work illustrates the development of a low-cost wireless sensor tag that could be placed in packaged medical products to accurately monitor level radiation exposure during sterilization process.
Inflammatory Bowel Disease (IBD) has become alarmingly prevalent in the last two decades affecting 6.8 million people worldwide with a starkly high relapse rate of 40% within 1 year remission. Existing visual endoscopy techniques rely on subjective assessment images that are error-prone and insufficient indicators early-stage IBD, rendering them unsuitable for frequent quantitative monitoring gastrointestinal health necessary detecting regular relapses IBD patients. To address these...
Abstract Non‐invasive smart electronic‐free sampling capsules have revolutionized the exploration of microbiome‐disease interactions in inaccessible regions gastrointestinal (GI) tract. However, a significant impediment to broader use is challenge reliably tracking and determining their vivo location. Variability patient motility introduces uncertainties capsule position. Thus, there critical need for effective solutions that ensure traceability microbiome studies employing such capsules....
Abstract To address growing water scarcity, we must improve the energy efficiency of thermal desalination technologies such as air gap membrane distillation. However, promising functional materials slippery liquid infused porous surfaces have not yet implemented for any technology. Here, fabricate and test (using Krytox 16,256 lubricant CuO nanostructures) in an distillation apparatus. System-level transport models, validated by experimental data, establish a framework improving performance...
A tuneable laser-induced oxidation technique was demonstrated for the fabrication of binder-free and robust electroactive copper oxide film as a highly sensitive non-enzymatic glucose sensor.
Here we report a simple approach to increase the stability performance of all-solid-state electrochemical sensors by improving interfacial bonding between ion selective membrane and electrode through cold atmospheric plasma surface treatment.
Although serum and fecal biomarkers (e.g., lactoferrin, calprotectin) have been used in management distinction between inflammatory bowel disease (IBD) irritable syndrome (IBS), none are proven to be a differential diagnostic tool Crohn's (CD) ulcerative colitis (UC). The main challenge with laboratory-based the stool test is inability indicate location of disease/inflammation gastrointestinal (GI) tract due homogenous nature collected sample. For first time, we designed developed...
Abstract Currently, one of the main environmental concerns is toxicity caused by arsenic. Arsenic-polluted water can cause many human health problems including various cancerous diseases. In natural water, inorganic arsenic be found in forms arsenite and arsenate, which have been several Iranian provinces – e.g., East Azerbaijan, Kurdistan, city Bijar high concentrations. Modern nanofiltration (NF) technology enables a wide range resource pollutants to controlled efficiently. this study, an...
