Existing affinity-based fluorescence biosensing systems for monitoring of biomarkers often utilize a fixed solid substrate immobilized with capture probes limiting their use in continuous or intermittent biomarker detection. Furthermore, there have been challenges integrating biosensors microfluidic chip and low-cost detector. Herein, we demonstrated highly efficient movable fluorescence-enhanced platform that can overcome the current limitations by combining enhancement digital imaging....
Abstract The on‐body immunodetection of biomarkers in sweat would significantly augment the potential wearable body‐interfaced biosensors for self‐testing but has been limited due to difficulty integrating liquid handling and immunobiosensing devices a platform. Herein, stretchable microfluidic immunobiosensor (SMIB) patch with hollow microfibers elastomeric nanocomposites highly sensitive biosensing neuropeptide Y (NPY), stress biomarker, human is reported. SMIB composed device an...
Abstract Research on transient wearable electronics with stretchable components is of increasing interest because their abilities to conform seamlessly human tissues and, more interestingly, disappear from the environment when disposed. To wear them comfortably, component materials must be pliable, tough, stretchable, biocompatible, and disintegrable. However, most biodegradable are not or limiting use in electronics. Herein, these challenges addressed by demonstrating a nanofiber...
Abstract To create artificial visual perception systems, retina structures that can imitate the behavior of biological in human vision are great interest. However, these devices have limited abilities to emulate structure and working principles retinas fiber‐shaped optic nerves. Here, a bio‐inspired based on fibrous photonic synapse (FPAS) formed by organic–inorganic heterojunctions single fiber is proposed. The two‐terminal FPAS principle retina, nerves, synaptic functions neurons. proposed...
In this study, Mo3Se3– single-chain atomic crystals (SCACs) with atomically small chain diameters of ∼0.6 nm, large surface areas, and mechanical flexibility were synthesized investigated as an extracellular matrix (ECM)-mimicking scaffold material for tissue engineering applications. The proliferation L-929 MC3T3-E1 cell lines increased up to 268.4 ± 24.4% 396.2 8.1%, respectively, after 48 h culturing SCACs. More importantly, extremely high was observed when the cells treated 200 μg mL–1...
Stretchable and transparent nanofiber-networked electrode.
Accurate, onsite detection of pathogenic bacteria from food matrices is required to rapidly respond pathogen outbreaks. However, accurately detecting whole-cell in large sample volumes without an enrichment step remains a challenge. Therefore, bacterial samples must be concentrated, identified, and quantified. We developed tunable magnetic capturing cartridge (TMCC) combined it with portable digital fluorescence reader for quick, onsite, quantitative Staphylococcus aureus. The TMCC platform...
Many physiochemical properties of the extracellular matrix (ECM) muscle tissues, such as nanometer scale dimension, nanotopography, negative charge, and elasticity, must be carefully reproduced to fabricate scaffold materials mimicking tissues. Hence, we developed a tissue ECM-mimicking using Mo6S3I6 inorganic molecular wires (IMWs). Composed bio-essential elements having nanofibrous structure with diameter ∼1 nm surface charge high stability, IMWs are ideal for natural ECM molecules. Once...
Biodegradable stretchable electronics have demonstrated great potential for future applications in and can be resorbed, dissolved, disintegrated the environment. Most biodegradable electronic devices used flexible materials, which limited conformality wearable implantable devices. Here, we report a biodegradable, biocompatible, composite microfiber of poly(glycerol sebacate) (PGS) polyvinyl alcohol (PVA) transient device applications. Compositing high-strength PVA with PGS poor...
