DOCUMENT TYPE: Journal CA Section: 66 (Surface Chemistry and Colloids) Section cross-reference(s): 73, 78 Electronic and geometric properties of Cr oxide nanowires deposited on self-assembled block copolymer templates are evaluated by synchrotron radiation based spectroscopic methods like XPS and x-ray absorption spectroscopy (XAS). The geometric distribution of the nanowires is monitored with x-ray photoelectron emission microscopy (XPEEM) and at. force microscopy (AFM). XAS and XPS of Cr 2p emissions for Cr oxide nanostructures det. an oxidn. state different from the most common Cr oxides and addnl. satellite peaks are derived from localization effects induced by the nanostructuring. .

Bioaffinity sensor with binding protein

Bioaffinity sensor with binding protein. Ikariyama, Y.; Furuki, M.; Aizawa, M. (Inst. Mater. Sci., Univ. Tsukuba, Ibaraki 305, Japan). Anal. Chem. Symp. Ser., 17(Chem. Sens.), 693-8 (English) 1983. CODEN: ACSSDR. ISSN: 0167-6350. DOCUMENT TYPE: Journal CA Section: 9 (Biochemical Methods) Section cross-reference(s): 72 A newly developed bioaffinity sensor for biotin with a binding protein (avidin) is described. The sensor is composed of a Clark-type O electrode on which is placed a polymer membrane with immobilized 2-(4'-hydroxyphenylazo)benzoic acid (I) which complexes with catalase-labeled avidin. 1634-82-8 and 89919-24-4 are also in the experiment. The mol. complex between I and avidin on the membrane easily dissocs. to form a stable complex between biotin and avidin in soln. when the sensor is contacted with biotin soln. The catalase which remains bound on the membrane reduces H2O2 in soln., and the O produced is detected by the O electrode and related to biotin concns. in the range 10-8-10-5 g/mL. Since the sensing depends on the difference in bioaffinity, the sensor is termed a bioaffinity sensor. .
