title = "pH sensor using protein-mediated gold nanocrystal array",
abstract = "pH sensitivity of protein mediated gold nanocrystals modified SiO 2 have been investigated using a capacitive EIS (electrolyte- insulator-semiconductor) structure and compared with bare SiO2. The SiO2 surface was first silanized using phenyltriethoxy and then a chaperonin protein array was formed on SiO2 surface. Finally, the chaperonin protein lattice is used to deposit gold nanocrystal on SiO 2 surface in the EIS structure. The electrochemical characterization of EIS sensors was done by means of C-V measurement in pH buffer solutions of values from 2 to 12. The average sensitivity of gold modified SiO2 senor was 33 mV/pH and SiO2 senor was 35 mV/pH while the linearity was 99.37% and 98.35%, respectively.",
