A new fluorescence-micro-imaging system has been built using the microfluidic chip. By using this system fluorescence ratio of calcium ion (Ca2 + ) in cells were measured. Cell fostering, staining and driving can be implemented on the designed microfluidic chip. Then we make use of 340nm or 380nm laser to excite the calcium ion (Ca2 + ) and enable it emit fluorescence. The image of fluorescence was...
In the presence of cucurbit[7]uril (CB[7]), the CB[7] could react with palmatine, which served as a sensitive fluorescence probe, to form host‐guest stable complexes and the fluorescence intensity of the complexes was greatly enhanced. The fluorescence intensity decreased linearly with an increasing number of L‐cystine in the inclusion system. The experimental results show that there exists a competition...
The research develops the vehicle being used to measure the friction coefficients of airstrip. The measuring system is mainly composed of machinery system and electrical equipment system. Among them, the machinery system accomplishes the actions such as the speed's transferring, the measuring wheel's lift and falling and watering, etc. And the electrical equipment system is composed of PLC as a slave,...
In this paper, an effective, convenient and cheap computerized microscopic system was developed to measure cell fluorescence quantitatively. A series of experiments were given to measure relative fluorescence intensity of DNA ploidy in mouse spermatozoa and hepatocytes, static [Ca2+]i (concentration of Ca2+) in single nerve cell and the change of [Ca2+]i in a nerve cell subjected to high K+ or glutamate...
