Bacteriophages are ideal recognition elements for bacterium because of specificity and high affinity in the field of biosensors. The effect of bimolecular immobilization directly influences the performance of biosensors, so orientation immobilization of bacteriophages is of great importance to the biosensors. This article reviews the recent progress in biosensors that used a variety of strategies...
This study presents combination of advantages in MEMS technology and molecular methods for detection of methicillin resistant gene, mecA, in Staphylococcus aureus. A disposable MEMS DNA biosensor was designed and fabricated for optical and electrochemical detections. Adsorption of DNA on gold electrode was examined theoretically and experimentally. In theoretical studies, Lennard Jones potential energies...
A novel nano Fe3O4-Au modified amperometric immunosensor for rapid separation-free determination of human immunodeficiency virus (HIV) p24 antigen in acquired immunodeficiency syndrome (AEDs) patients' serum is proposed. Firstly, one novel sebacato-bridged Cu(II) phen complex Cu(phen)L2 (referred to as CuL, H2L=sebacic acid; phen=1,10phenanthroline) was absorbed on the surface of glassy carbon electrode...
We report investigations on the adsorption and in-vitro recrystallization kinetics of the bacterial surface layer protein of Bacillus sphaericus NCTC 9602 on gold surfaces by means of film bulk acoustic resonators. The acoustic resonators were operated in shear mode at about 800 MHz. From the measured changes of frequency and in dissipation, the mass and the viscoelasticity of biomolecular films formed...
