A new method of transferring micro/nanostructured films using gel as a transfer carrier is developed, which could transfer the films from their parent substrates to a variety of surfaces, even onto the inner wall of some containers. The advantages of this method over a traditional transfer are the ease of processing and the potential for the alteration of the transfer conditions. Agarose was used...
This paper describes a glucose biosensor based on glucose oxidase (GOx) immobilized on porous ZnO/Au electrodes. The ZnO porous electrodes were fabricated by electrochemical deposition of zinc oxide on patterned Au electrodes using polystyrene (PS) spheres as templates. Uniform pore size and highly ordered ZnO pore arrangement were observed from SEM images. X-ray diffraction (XRD) patterns revealed...
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...
Capacitive humidity sensors were fabricated using countersunk interdigitated electrodes coated with amorphous nanostructured TiO2, SiO2, and Al2O3 thin films grown by glancing angle deposition. The capacitive response and response times for each sensor were measured. The sensor utilizing TiO2 exhibited the largest change in capacitance, increasing exponentially from ~ 1 nF to ~ 1muF for an increase...
