This study demonstrates the advantage of Dip-Pen Nanolithography (DPN) as a research and design tool for metal nano-structure fabrications. We design two different gold nano-structures, which are fabricated by DPN etching method with temperature and humidity control. The plasmon resonance frequencies of both structures are measured with dark field scattering spectroscopy. Our results show that with...
We developed a glucose fiber sensor for measuring the glucose concentration in serum with heterodyne interferometry. The best response time and the resolutions of the fiber sensor are 1.3 seconds and 0.152 mg/dl, respectively. Besides, the fiber sensor can be reused more than 10 times.
A fiber-type glucose sensing system is presented which combined single-mode fiber conjugated with glucose oxidase (GOD) and heterodyne interferometry. Based on the optical setup, the absolute glucose concentration can be obtained by measuring the phase difference coming from the chemical reaction between the glucose and GOD on the fiber sensor. Cause of the achievement of the absolute glucose concentration...
