“…Atom transfer radical polymerization (ATRP) reactions have been widely used in biosensing systems due to their ease of handling and controllability [26]. Activator regenerative electron transfer atom transfer radical polymerization (ARGET ATRP) is an improved technique for atom transfer radical polymerization [27,28]. It does not require a high concentration of heavy metal catalysts to overcome irreversible radical termination, nor does it require an anaerobic environment, only a low concentration of catalysts [29,30].…”

Early and sensitive detection of tobacco mosaic virus (TMV) is of great significance for improving crop yield and protecting germplasm resources. Herein, we constructed a novel fluorescence sensor to detect TMV RNA (tRNA) through double strand specific nuclease (DSN) cycle and activator regenerative electron transfer atom transfer radical polymerization (ARGET ATRP) dual signal amplification strategy. The hairpin DNA complementarily paired with tRNA was used as a recognition unit to specifically capture tRNA. By the double‐stranded DNA hydrolyzed with DSN, tRNA is released to open more hairpin DNA, and more complementary DNA (cDNA) is bound to the surface of the magnetic beads (MBs) to achieve the first amplification. After binding with the initiator, the cDNA employed ARGET ATRP to attach more fluorescent signal molecules to the surface of MBs, thus achieving the second signal amplification. Under the optimal experimental conditions, the logarithm of fluorescence intensity versus tRNA concentration showed a good linear relationship in the range of 0.01–100 pM, with a detection limit of 1.03 fM. The limit of detection (LOD) was calculated according to LOD = 3 N/S. Besides, the sensor showed good reproducibility and stability, which present provided new method for early and highly sensitive detection for plant viruses.

“…to TCF and 3F-TCF acceptors with stronger and more stable electron withdrawing abilities, as well as the newly discovered 5F-TCF acceptors in recent years. 27 TCF and 3F-TCF acceptors were the two most widely used acceptors in the D-p-A structure, 28 and there were still few reports on 5F-TCF acceptors. 29,30 At present, host-guest doping is still the most widely studied organic electro-optical material system, occupying an important position in second-order nonlinear optical materials.…”

“…Nonetheless, technological limitations prevented the resolution of issues related to wide dynamic range pressure identification, recycling, and long-term storage. [25,26] Therefore, the development of an accurate visual pressure sensing device, integrating the two functions through suitable composite materials and effective structural modifications, is urgently needed.…”

Most current visual pressure sensing devices are greatly limited by less integrated functions. To address this issue, a multi‐dimensional pressure interactive visual monitoring device is proposed based on the temperature and humidity adaptive hydrogel. Specifically, this device is composed of a buffer grid layer that divides it into pressure sensing and luminous display areas. With a double network structure incorporated with a LiBr liquid, the pressure sensing area demonstrates great deformability, resilience, and self‐absorption. In a dynamic mode, the best pressure can be detected at high humidity and low temperature, displaying a range of up to 45 N and offering feedback at a minimum load of 0.25 N. Importantly, the device remaines excellent performance after the dynamic compression repeating over 1300 cycles. In static mode, MPI‐ACEL achieves a delay time of up to 390 min. Finally, it is anticipated that this multifunctional device will provide a new, flexible, and effective scheme for visual pressure sensing, environmental adaptive directional indication, and multi‐dimensional remote monitoring.
