Synthesis and Characterization of DNA-Modified Silicon (111) Surfaces
Abstract
Hydrogen-terminated Si(111) surfaces are modified by attachment of oligodeoxynucleotides and characterized with respect to DNA surface density, chemical stability, and DNA hybridization binding specificity. Surface functionalization employs the reaction of ω-unsaturated alkyl esters with the Si(111) surface using UV irradiation. Cleavage of the ester using potassium tert -butoxide yields a carboxyl-modified surface, which serves as a substrate for the attachment of DNA by means of an electrostatically adsorbed layer of polylysine and attachment of thiol-modified DNA using a heterobifunctional cross-linker. The resultant DNA-modified surfaces are shown to exhibit excellent specificity and chemical stability under the conditions of DNA hybridization. This work provides an avenue for the development of devices in which the exquisite binding specificity of biomolecular recognition is directly coupled to semiconductor devices.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
