The n-Si (111) was silanized by treating it with low molecular weight octyltrichlorosilane in toluene. Scanning tunneling microscopy (STM) image of lambda-DNA on octyltrichlorosilane deposited Si substrate shows areas exhibiting arrayed structures of 700 nm length and 40 nm spacing. Scanning tunneling spectroscopy (STS) at different stages depict a broad distribution of defect states in the bandgap region of n-Si(111) which presumably facilitates tunneling through otherwise insulating DNA layer.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">National Review and Coordination Meeting on Nanoscience and Nanotechnology, Hyderabad, INDIA, 2007</style></notes><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">0.944</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Kulkami, Sneha A.</style></author><author><style face="normal" font="default" size="100%">Ogale, Satishchandra B.</style></author><author><style face="normal" font="default" size="100%">Vijayamohanan, Kunjukrishanan P.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Tuning the hydrophobic properties of silica particles by surface silanization using mixed self-assembled monolayers</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Colloid and Interface Science</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">alkyltrichlorosilane</style></keyword><keyword><style  face="normal" font="default" size="100%">silanization</style></keyword><keyword><style  face="normal" font="default" size="100%">silica particles</style></keyword><keyword><style  face="normal" font="default" size="100%">superhydrophobicity</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2008</style></year><pub-dates><date><style  face="normal" font="default" size="100%">FEB</style></date></pub-dates></dates><number><style face="normal" font="default" size="100%">2</style></number><publisher><style face="normal" font="default" size="100%">ACADEMIC PRESS INC ELSEVIER SCIENCE</style></publisher><pub-location><style face="normal" font="default" size="100%">525 B ST, STE 1900, SAN DIEGO, CA 92101-4495 USA</style></pub-location><volume><style face="normal" font="default" size="100%">318</style></volume><pages><style face="normal" font="default" size="100%">372-379</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;Here we describe a novel method of preparing hydrophobic silica particles (100-150 nm; water contact angle of dropcasted film ranging from 60 degrees to 168 degrees) by surface functionalization using different alkyltrichlorosilanes. During their preparation, the molecular surface roughness is also concurrently engineered facilitating a change in both the surface chemical composition and the geometrical microstructure to generate hierarchical structures. The water contact angle has been measured on drop-cast film surface. The enhancement in the water contact angle on 3D (curved) SAMs in comparison to that on 2D (planar) surface is discussed using the Cassie-Baxter equation. These silica particles can be utilized for many potential applications including selective adsorbents and catalysts, chromatographic supports and separators in microfluidic devices.
