development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

simulation and design of electronic processing circuit for restaurants e-procurement system

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...

measuring viscoelastic properties of Red Blood Cell using optical tweezers

Efforts have been made to study the behavior of complex materials in micrometer dimensions with various techniques. One of these methods is the use of optical tweezers for biophysical applications. Red blood cells, as the most abundant blood-forming cells, play an important role in the life of living organisms, and their unique mechanical properties are important. In this report, the study of s...

Optical constant of CoFeB thin film measured with interference enhancement method

Optical constants (n and k) of Co20Fe60B20 (CoFeB) thin films (2~40nm) are measured by using interference enhancement method with spectroscopic ellipsometry in the wavelength range of 270~1600nm. The effects of film thickness, protection layer and annealing process on the optical constant of CoFeB film are investigated. In the range of 40~10nm, both n and k decrease with the decrease of thickne...
