Cmos-based Luminescent Co2 Sensor
In this work, we demonstrate a portable optical CO2 sensor using CMOS image sensing with polarization signal isolation. Luminescent CO2 detection methods generally exhibit faster response time and increased sensitivity over the established commercial sensors (NDIR, electrochemical), but require bulky and expensive spectrophotometry equipment which confines them to a lab. Components used in our ...
متن کاملCMOS Chip as Luminescent Sensor for Biochemical Reactions
We describe a novel biochemical sensing method and its potential new biosensing applications. A light-sensitive complementary metal oxide semiconductor (CMOS) chip prepared through a standard 0.5m CMOS process was developed for measuring biochemical reactions. A light producing enzymatic reaction catalyzed by horseradish peroxidase (HRP) was designed as a platform reaction to determine the conc...
متن کاملPlanar nitric oxide (NO)-selective ultramicroelectrode sensor for measuring localized NO surface concentrations at xerogel microarrays.
A planar ultramicroelectrode nitric oxide (NO) sensor was fabricated to measure the local NO surface concentrations from NO-releasing microarrays of varying geometries. The sensor consisted of platinized Pt (25 microm) working electrode and a silver paint reference electrode coated with a thin silicone rubber gas permeable membrane. An internal hydrogel layer separated the Pt working electrode ...
متن کاملInkjet-printed multicolor arrays of highly luminescent nanocrystal-based nanocomposites.
Inkjet technology is a compelling method for the flexible and cost-effective printing of functional inks. We show that nanocomposite solutions based on polystyrene and differently sized core/shell-type nanocrystals (NCs) formed by a CdSe core coated with a shell of ZnS (CdSe@ZnS) in a single solvent, chloroform, can be reliably dispensed into luminescent, multicolor pixel arrays. This study dem...
متن کاملMultianalyte pin-printed biosensor arrays based on protein-doped xerogels.
We report the first biosensor arrays based on pin printing protein-doped xerogels. The individual biosensor elements are on the order of 100 microm in diameter. Arrays are formed (1) onto a planar substrate that is excited by an external source (laser) or (2) directly on the face of a light-emitting diode. We illustrate the potential of our approach by fabricating, testing, and characterizing f...
