Morphology control significantly improves the microstructure, increases the number of defects, tailors porosity, and optimizes the band gap of gas-sensing materials, profoundly affecting the adsorption and desorption capabilities for gas molecules. Herein, we prepared In(OH)3 precursors via a hydrothermal method and rationally controlled the microstructure of In2O3 by varying annealing temperatures

Evaporation poses a significant challenge in digital microfluidic (DMF) systems, especially when microdroplets are exposed to air. Evaporation can increase substance concentration, resulting in distorted detection outcomes and even causing cell apoptosis. In our research, we systematically evaluated the effects of various factors on droplet evaporation rates, including path length, encapsulation (gap

Simultaneous analysis of multiple protein and nucleic acid biomarkers in one clinical sample can provide clinically valuable results for the diagnosis, monitoring, and management of diseases. However, current diagnostic platforms primarily rely on the independent detection of proteins and nucleic acids, which is time-consuming and labor-intensive.In this study, we propose a microfluidic chip system

Oxide chemiresistors have gained considerable attention for detecting warfare nerve agents such as sarin gas over the years, yet have failed to materialize due to poor selectivity. To address this challenge, we presented the design of a bilayer DMMP chemiresistor, where using Au nanoparticles (NPs)-loaded ZnFe2O4 as sensing layer, and zeolite as filtering layer, for detecting dimethyl methylphosphonate

The selectivity of semiconductor sensors has effectively improved with the development of temperature modulation technology. However, because the information of the single component gas in the multicomponent gas is mixed in the dynamic response curves, recognizing multicomponent gas types and concentrations remains a longstanding challenge. Inspired by blind source separation (BSS) theory, strong separation

Ammonia (NH3) detection has an essential role in environmental monitoring, industrial safety, and medical diagnostics, particularly in the early-stage detection of possible diseases from human breath. In this study, we comprehensively investigated various gas sensors, focusing on the characteristics of an NH3 gas sensor prepared using pure ZnO and polyaniline (PANI) and their nanocomposites at room

The rapid and efficient detection of biomarkers in interstitial fluid (ISF) represents a compelling alternative to traditional invasive blood sampling for diagnostic and monitoring purposes. Here, bio-inspired microneedles (MNs) with hierarchical microchannels (HMC-MNs), emulating the liquid transport properties of Sarracenia trichomes, are presented. These MNs are fabricated using a secondary mold

Chimeric antigen receptor T cell (CAR-T) therapy has recently gained recognition as a transformative treatment of cancer, particularly of hematological malignancies. However, CAR-T manufacturing remains a major bottleneck of this treatment modality; in standard cases, it takes up to two weeks, resulting in a phenotypic shift toward terminally differentiated T-cells and a significant depletion of T-cells
