Utilizing an Automated SERS-Digital Microfluidic System for High-Throughput Detection of Explosives

ACS Sensors, Год журнала: 2023, Номер 8(4), С. 1733 - 1741

Опубликована: Март 23, 2023

The surface-enhanced Raman scattering (SERS) technique is a promising method for the detection of explosives such as 2,4,6-trinitrotoluene (TNT) and 3-nitro-1,2,4-triazol-5-one (NTO) because its high sensitivity to trace substances. However, most SERS processes are often nonautomated well exhibit low efficiency toxic exposure, which poses potential danger operators. Herein, we propose integration with digital microfluidics (SERS-DMF) automated, high-throughput, high-sensitivity explosives. First, carefully designed DMF chip comprising 40 drive electrodes 8 storage achieve high-throughput process. And different concentrations target molecules, silver nanoparticles (Ag NPs), salts were loaded into chip. Then, droplet aggregation, incubation, automatically controlled using SERS-DMF platform. In addition, Ag NPs efficiently aggregated by screening types salts, resulting in "hotspots" effect. With help platform, two explosive samples detected throughput sensitivity. limits TNT NTO 10–7 10–8 M, respectively. compared nonautomatic operations, platform exhibited better reproducibility higher proposed thus has considerable an analytical detecting hazardous

Ultrasensitive and On‐Site Detection of Nitroaromatic Explosives Through a Dual‐Mode Hydrogel Sensor Utilizing Portable Devices

Advanced Functional Materials, Год журнала: 2024, Номер 34(37)

Опубликована: Апрель 21, 2024

Abstract The development of straightforward and dependable explosive sensors for on‐site identification is essential to preserving public safety concerns lowering the risks related explosions. However, one main barriers advancement explosives detection in future complexity process. Here, a flexible hydrogel‐based sensing platform based on 3,4‐bis (4‐(1,2,2‐triphenylvinyl) phenyl) thiophene (TPE‐Z) methyl red design concept shown that simultaneously achieves all targeted properties, including being quick, portable, reliable, resistant external interference. This composite fluorescent probe demonstrates outstanding capabilities, low limits (0.48 mg L −1 ) rapid response times (<5 s), which can be combined with smartphones 2,4,6‐trinitrophenol (picric acid, PA) detection. Two independent fluorescence colorimetric channels sensor showed selective PA under visible light irradiation, respectively. Meanwhile, hydrogel sensor's distinct “turn on” off” modes utilized construct “YES” “NO” logic gates, subsequently proves they employed differentiate on‐site. envisaged offer in‐depth insights advancing nitroaromatic explosives.
