“…(11,12) Currently, most of the light sources used in the reported crosslinkers can be categorized into two types: UV lamps and UV light-emitting diodes (LEDs). (13)(14)(15)(16)(17)(18)(19) In the UV lamp crosslinkers, although a large irradiation area can be covered by parallel distributed lamps, the low irradiation efficiency caused by heat generation and the slow response hinder their use in real-time crosslinking scenarios. (13) Owing to the advantages of high luminescence efficiency, fast response, and wide wavelength range, UV LEDs have attracted much interest from academia and industry since 1998.…”

“…The use of the Bluetooth communication stack improved the real-time performance of the crosslinker but also brought an extra cost of the development and size of the instrument. (19) To overcome the aforementioned shortcomings and limitations, we have developed a novel palm-sized UV LED crosslinker as reported in this paper. We discarded the Bluetooth microcontroller and instead used a regular microcontroller and Wi-Fi module to reduce the instrument size to half that in our previous work.…”

To satisfy the requirement of microarray fabrication in optical sensing applications, we report a palm-sized UV LED crosslinker. By employing a microcontroller and the Wi-Fi communication technique, a sequence of different wavelengths, irradiation intensities, and crosslinking durations can be programmed by an Android app. To evaluate the irradiation uniformity of the crosslinker, we immobilized an array of fluorescent-labeled proteins on a silver substrate of high flatness by the reported crosslinker in 8 s and measured the fluorescence intensity throughout the array. For protein spots of the same concentration, the intensity difference is around 10% of the average value. The results show that the reported UV LED crosslinker can help to achieve the uniform and efficient immobilization of a protein microarray.

Reinforced concrete structures are widely used in modern buildings such as buildings, bridges, and tunnels. However, the structural damage caused by reinforcement corrosion seriously affects the service life of the buildings. Because the corrosion of reinforcement in concrete is a very slow process, the continuous detection of reinforcement corrosion is very important. In view of the slow development of steel corrosion detection equipment in China, which cannot meet the application requirements of concrete structures in China, wireless monitoring technology has more advantages than traditional monitoring technology. In this paper, combined with wireless transmission technology, a concrete reinforcement corrosion detection system based on wireless sensor network is designed. Embedded sensors based on the principle of electromagnetic coupling are used to collect steel corrosion information. It is determined that the 16-bit ultralow power consumption microcontroller MSP430F149 is the main control chip, the AD9850 based on DDS technology is the signal generation chip, and the nRF905 is the detection circuit scheme of the wireless transceiver chip. The star network is determined by polling the entire network topology and MAC protocol. The embedded sensor is designed through simulation. This article discusses the principle of using embedded sensors to detect steel corrosion and determines the feasibility of its low-cost implementation. The embedded sensor and steel corrosion detection system were tested. The simulation method of the embedded sensor is verified through actual measurement. The test results show that the system network is normal and all parts work stably, which can meet the requirements of the project.

In this work, we report performance optimization of a wireless sensor network (WSN) based on the plain silver surface plasmon resonance imaging (SPRi) sensor. At the sensor node level, we established the refractive index-thickness models for both gold and silver in the sensor and calculated the depth-width ratio (DWR) and penetration depth (PD) values of the sensor of different gold and silver thicknesses by the Jones transfer matrix and Kriging interpolation. We optimized the DWR and PD simultaneously by using the multi-objective optimization genetic algorithm (MOGA). In the following performance optimization of WSN, we simultaneously optimized the transmission success rate and information dimension with the number of nodes and transmission failure rate of the sensor node as variables by the same algorithm. By calculating the information dimension and the transmission success rate of each Pareto optimal solution, we obtained the number of nodes and transmission failure probability of the node available for practical deployment of WSN. The above results indicate that the Pareto optimal solution set obtained from MOGA can help to provide the best solution for the optimization of some certain performance parameters and also assist us in making the trade-off decision in the structure design and network deployment if optimal values of all the performance parameters can be obtained simultaneously.
