Exploration of clinically acceptable blood glucose monitors has been engaging in the past decades, yet ability to quantitatively detect a painless, accurate, and highly sensitive manner remains limited. Herein, fluorescence-amplified origami microneedle (FAOM) device is described that integrates tubular DNA-origami nanostructures oxidase molecules into its inner network monitor glucose. The skin-attached FAOM can collect situ transfer input proton signal after oxidase's catalysis....
Voices have unique acoustic signatures, contributing to the variability listeners must contend with in perceiving speech, and it has long been proposed that normalize speech perception information extracted from a talker's speech. Initial attempts explain talker normalization relied on extraction of articulatory referents, but recent studies context-dependent auditory suggest general referents such as long-term average spectrum (LTAS) similarly affect perception. The present study aimed...
Tendon and ligament ruptures are prevalent, severe sports injuries require surgical repair. In clinical practice, monitoring of tissue strain is critical to alert postoperative complications such as graft reinjury loosening. Here, we present a sensor system that integrates communication coil onto silk sutures, enabling in situ wireless readout strains via implantation. The flexible shows excellent adaptability soft tissues, providing range 0 10% with minimum detection threshold 0.25%...
In bioanalysis, precisely isolating liquid reactions in distinct systems or at different temporal sequences is vital for ensuring accurate results devoid of crosstalk. However, passive isolation unattainable through existing microfluidic valves. Here, bridge cutting valves (LBCVs) are introduced to automatically segregate liquids by establishing airlocks, offering an innovative structure distribution. The principle breakup studied and applied the design LBCVs. Additionally, monolithic chips...
Thermotaxis has been demonstrated to be an important criterion for sperm evaluation, yet clinical assessment of thermotaxis capacity is currently lacking. In this article, the on-chip evaluation human presented first time using interfacial valve-facilitated microfluidic device. The temperature gradient was established and accurately controlled by external control system. responsive population enriched into one branch channels with higher setting non-responsive ones were evenly distributed...
In sexual assault cases, forensic samples are a mixture of sperm from the perpetrator and epithelial cells victim. To obtain an independent short tandem repeat (STR) profile perpetrator, must be separated cells. However, current method used in crime laboratories, namely, differential extraction, is time-consuming labor-intensive process. achieve rapid automated sample pretreatment process, we fabricated microdevice for hydrodynamic size-based separation When suspension were introduced into...
Artifacts removal and rhythms extraction from electroencephalography (EEG) signals are important for portable wearable EEG recording devices. Incorporating a novel grouping rule, we proposed an adaptive singular spectrum analysis (SSA) method artifacts extraction. Based on the signal amplitude, rule determines adaptively first one or two SSA reconstructed components as removes them. The remaining then grouped based their peak frequencies in Fourier transform to extract desired rhythms. thus...
A sheath-less PDMS microfluidic IFC device with a simple structure was constructed, good performance in single-cell detection. The electrical conductance and susceptance were used to differentiate the beads/cells.
Abstract The trend of incorporating soft electronic systems in current electronics framework is fast becoming a wide phenomenon healthcare as they provide more suitable human‐machine interface making it conveniently possible to achieve real‐time, continuous health monitoring and therapy. However, the effective integration an entire system with dynamic human skin has proven be strenuous task since combination existing hard components materials difficult realize. Here, reported method...
Iron oxides recovered from abandoned coal mine drainage (AMD) sites (Lowber, Scrubgrass, and Horner) as a soil amendment were investigated in this laboratory study for their effectiveness the stabilization of cadmium, copper, zinc two metal-contaminated soils. The adsorption experimental results demonstrated that all three AMD iron possess significant capacity Cd(II), Cu(II), Zn(II). Horner oxide exhibited highest capacity. Both extraction showed metal sequestration enhancement through...
A number of studies have demonstrated links between linguistic knowledge and performance in math. Studies examining these first language speakers English traditionally relied on correlational analyses tests standardized math tests. For second (L2) speakers, the majority compared proficient non-proficient English. In this study, we take a novel approach examine features student while they are engaged collaborative problem solving within an on-line tutoring system. We transcribe students'...
The selection of high-quality sperm is essential to the success in vitro fertilization (IVF). As human cervical mucus has a high viscosity, without enough swimming persistence, clouds cannot arrive at ampulla fertilize egg. In this study, we used capability and motion characteristics that are known be associated with ability evaluate quality sperm. Here, clinically applicable polymethyl methacrylate (PMMA)-based microdevice was designed fabricated for evaluation screening persistence viscous...
Nowadays, transdermal drug delivery has become a hot topic with regard to delivery.
