Influence of postdeposition annealing on the structural and optical properties of sputtered zinc oxide film
Vinay Gupta,Abhai Mansingh +1 more
TL;DR: The influence of postdeposition annealing on the structural and optical properties of rf sputtered insulating zinc oxide films has been investigated in this article, where the optical dispersion data have been fitted to (1) a single oscillator model and (2) the Pikhtin-Yas'kov model.
Journal ArticleDOI
Recent advances in ZnO nanostructures and thin films for biosensor applications: review.
Sunil K. Arya,Shibu Saha,Jaime E. Ramirez-Vick,Vinay Gupta,Shekhar Bhansali,Surinder P. Singh +5 more
TL;DR: ZnO nanostructures have shown the binding of biomolecules in desired orientations with improved conformation and high biological activity, resulting in enhanced sensing characteristics, and compatibility with complementary metal oxide semiconductor technology for constructing integrated circuits makes ZnO Nanostructure suitable candidate for future small integrated biosensor devices.
Journal ArticleDOI
Response speed of SnO2-based H2S gas sensors with CuO nanoparticles
TL;DR: In this article, the authors used CuO nanoparticles on sputtered SnO2 thin-film surface for trace level H2S gas detection and showed that the sensitivity of the sensor was high at a low operating temperature of 130 ˚C.
Journal ArticleDOI
Cholesterol biosensor based on rf sputtered zinc oxide nanoporous thin film
Surinder P. Singh,Sunil K. Arya,Pratibha Pandey,Bansi D. Malhotra,Shibu Saha,K. Sreenivas,Vinay Gupta +6 more
TL;DR: In this paper, cholesterol oxidase (ChOx) has been immobilized onto zinc oxide (ZnO) nanoporous thin films grown on gold surface and a preferred c-axis oriented ZnO thin film with porous surface morphology has been fabricated by rf sputtering under high pressure.
Journal ArticleDOI
Application of Thiolated Gold Nanoparticles for the Enhancement of Glucose Oxidase Activity
Pratibha Pandey,Surinder P. Singh,Sunil K. Arya,Vinay Gupta,Monika Datta,Sukhvir Singh,Bansi D. Malhotra +6 more
TL;DR: The covalently immobilized GOx thiolated nanoparticles exhibit a response time of 30 s, a shelf life of more than 6 months, and improved tolerance to both pH and temperature.
