Role of interfaces on the direct tunneling and the inelastic tunneling behaviors through metal/alkylsilane/silicon junctions. Aswal, D. K.; Petit, C.; Salace, G.; Guerin, D.; Lenfant, S.; Yakhmi, J. V.; Vuillaume, D. (Institut d'Electronique, de Microelectronique, et de Nanotechnologie, "Molecular Nanostructures & Devices" group, CNRS, Villeneuve d'Ascq 59652, Fr.). Physica Status Solidi A: Applications and Materials Science, 203(6), 1464-1469 (English) 2006 Wiley-VCH Verlag GmbH & Co. KGaA. CODEN: PSSABA. ISSN: 0031-8965. DOCUMENT TYPE: Journal CA Section: 66 (Surface Chemistry and Colloids) Section cross-reference(s): 76 The authors studied the influence of the end group of the alkylsilane mol. used in Self Assembled Monolayer (SAM) in Si/SAM/Metal junctions. By Inelastic Electron Tunneling spectroscopy (IETS), the authors showed the formation of a covalent bond between the mols. and the Au electrode in the case of a thiol terminated alkylsilane. By elec. characterizations, the thiol group at the interface avoids diffusion of Au into the mol. even for a 3. carbons chain. For this short mol., the authors obsd. pure tunnel conduction with barrier height at the monolayer/Si and monolayer/Au interfaces found to be resp. 2.14 and 2.56 eV. These values were obtained using Simmons equation with an effective mass parameter m* = 0.16me (me = mass of the electron). This extends the demonstration of the excellent tunnel dielec. behavior of these org. monolayers down to 3 C atoms with a thiol/Au bond at the interface. .

Immobilized polymeric microspheres: polyacrolein microspheres covalently bound in a monolayer structure onto glass surfaces

Immobilized polymeric microspheres: polyacrolein microspheres covalently bound in a monolayer structure onto glass surfaces. Margel, Shlomo; Dolitzky, Yehudit; Sivan, Orit (Dep. Chem., Bar-Ilan Univ., Ramat-Gan 52900, Israel). Colloids Surf., 62(3), 215-30 (English) 1992. CODEN: COSUD3. ISSN: 0166-6622. DOCUMENT TYPE: Journal CA Section: 38 (Plastics Fabrication and Uses) Section cross-reference(s): 9, 34 Materials composed of an unpacked monolayer of polyacrolein microspheres covalently bonded onto glass surfaces were prepd. and characterized. These surfaces were synthesized by the covalent binding of long- and short-chain length w-cyanoalkylsilane compds.In this article, certain chemicals are used. Some of their cas registry numbers are 7521-80-4 and 11032-79-4 onto glass substrates. The nitrile groups at the w position were then reduced to primary amino groups. Polyacrolein microspheres of 0.7 mm av. diam. were then bonded to the modified surfaces. The residual aldehyde groups of the immobilized microspheres can then be used for the covalent binding of amino ligands, e.g., proteins, in a single step and at physiol. pH (or any other desired pH). The binding kinetics of bungarotoxin to the immobilized microspheres was investigated. .
