The demand for efficient and accurate devices used for calibration has been put forward in recent years. The near-field measurement technology is a convenient and operability method to calibrate an acoustic transducer. The calibration of high frequency acoustic transducer has a bigger error due to the limit of the calibration equipment. A high frequency acoustic transducer calibration system is designed...
This paper presents a novel Ku-Band low profile antenna system for mobile sitcom. The antenna is designed in the shape of a four-to-one rectangle based on planar antenna array. The method of beam scanning tracking is used which is simple and efficient. The antenna can mechanically scan the communication satellite automatically from 0° to 90° in elevation and 360° coverage in azimuth, achieving remote...
This paper develops a multi-antibody array biochip for detection of different-grade bladder cancer cell lysates based on protein expression level. Two nanoprobes modified with antibodies, Galectin-1 (Gal-1) and Lactate Dehydrogenase B (LDH-B), were immobilized in an array manner by sequent DEP manipulation steps including focusing, guiding and trapping, therefore, two different protein levels can...
Dielectrophoresis (DEP) has been demonstrated the manipulations of bio-modified particles for biosensors, and the microelectrodes are mostly made of metal materials such as Au, Cu and Pt, etc. However, the metal electrodes could induce extra background noise as observed the DEP chip in a fluorescence microscope. Currently, the fluorescence response still dominates the indicators of immunoassays; therefore,...
