Development of new magnetic bead separation and purification instrument / 中国医疗器械杂志

The article describes the development of new magnetic bead separation and purification instrument. The main application of the instrument is to capture tubercle bacillus from sputum. It is a pretreatment instrument and provides a new platform to help doctors to diagnose bacillary phthisis. Not only could it be used for tubercle bacillus capturing, but also for gene, protein and cell separating and purification. Because the controller of the instrument is 16-bit single chip microcomputer, the cost could be greatly reduced and it will be widely used in China.

The development of new standard plane light source for calibration of biochip readers / 中国医疗器械杂志

Biochip reader is an important instrument for taking pictures of biochip. The accuracy of the instrument influences diagnosis of doctors. So it is important to reduce the nonuniformity of images and the error between the biochip readers. This paper describes the development of new standard plane light source, which can reduce the work load of calibration, improve the accuracy and speed of calibration, made the biochip readers more reliably.
