Detection of adsorbed cytochrome c on hydroxyapatite thick films using a microwave sensor

Abstract

An interdigitated microwave sensor was used to detect the adsorption of cytochrome c on hydroxyapatite thick films. Changes in the microwave spectral response were indicative of the presence of adsorbed cytochrome c. The sensitivity of the system was also evaluated using different protein loadings on the e films. The results suggest that the microwave sensor can be utilized to detect protein.
