Recently biosensors based on silicon nanowire field-effect transistors (SiNW-FETs) have drawn huge amounts of attention, due to their ultra sensitivity, selectivity, label-free and real-time detection abilities. As people know more and more knowledge of the structure and function of nucleic acid molecules, DNA detection has gained importance increasingly. Here, we briefly summarize major fabrication methods in synthesising SiNW-FETs and selectively describe some applications of SiNW-FET biosensors in DNA detection over the past few years. Some key results from each article are summarized, involving the concept and mechanism behind each sensor, with the aim of stimulating more efforts in developing SiNW-FET biosensors for detecting DNA.

The design of intelligent multi-parameter real-time monitoring system for the security of coal mine roof is introduced aiming at the status of monitoring system for mine roadway roof safety and supporting. Using advanced field-bus CAN technology and Ethernet fiber transmission technology can not only display the measurement data on-site and alarm, but also transmit the measured data through the monitor network of mine to the main monitoring station on the ground and the remote monitoring center for analysis and processing, so that the monitor in command center on the ground can real-time and remotely monitoring the security status on the roof. The actual application showed that the system had the capability of high communication speed, long transmission distance, anti-electromagnetic interference, reliable transmission, and high real-time. The system can play an active role in early warning to avoid the occurrence of coal mine roof disasters.

In order to improve the precision of the azimuth measured by mobile robot's electronic compass, this paper proposes a new calibration method based on Fourier Neural Network trained by Modified Particle Swarm Optimization (MPSO-FNN). This method makes use of Fourier Neural Network (FNN) to establish the error compensation model of electronic compass's azimuth, and introduces Modified Particle Swarm Optimization (MPSO) algorithm to optimize the weights of neural network. Thus the comparatively accurate error model of azimuth is obtained to compensate the output of electronic compass. This method not only has strong nonlinear approximation capability, but also overcomes the neural networks' shortcomings which are too slow convergence speed, oscillation, and easy to fall into local optimum and sensitive to the initial values. Experimental results demonstrate that after calibrated by this method, the range of azimuth error reduces to -0.35°~0.70° from -3.4°~25.2°, and the average value of absolute error is only 0.30°.

Because of strong coupling, nonlinear, and time-varying characteristics, it is difficult to control complex spacecraft. By means of combining with controlled object dynamics and performance requirements, characteristic modeling and control approach is an effective way to solve this problem. Aimed at the flexible satellites described by using characteristic modeling approach, with the help of fuzzy rules, fuzzy dynamic characteristic modeling method and intelligent adaptive controller are designed to control this complex spacecraft. Meanwhile, based on the satellite system simulation platform, we validate the correctness and efficiency of the proposed modeling and control method by comparing with the simulation results of the other similar methods.
