Microorganism detection and analysis using carbohydrate and lectin recognition

Methods of binding and detecting a microorganism on a solid substrate. The microorganism is bound on a solid substrate covalently bound to a capture agent having a saccharide moiety. A lectin capable of binding to the microorganism and the saccharide moiety of the capture agent is added to the sample to bind the microorganism on the solid substrate. Further provided are biosensor devices, such as a quartz crystal microbalance (QCM) device or a surface plasmon resonance (SPR) device, that incorporate the solid substrate for the detection of microorganisms.

Formation of self-assembled monolayers by chemisorption of derivatives of oligo(ethylene glycol) of structure HS(CH2)11(OCH2CH2)mOH on gold

This paper describes the preparation of oligo(ethylene glycol)-terminated alkanethiols having structure HS-(CH2)11(OCH2CH2)mOH (m = 3-7) and their use in the formation of self-assembled monolayers (SAMs) on gold. A combination of experimental evidence derived from X-ray photoelectron spectroscopy (XPS), measurement of contact angles, and ellipsometry implies substantial disorder in the oligo(ethylene glycol)-containing segment. The order in the -(CH2)11- group is not denned by the available evidence. The SAMs are moderately hydrophilic: θa(H2O) = 34-38°; θr(H2O) = 22-25°. A study of monolayers containing mixtures of HS(CH2)11CH3 and HS(CH2)11(OCH2CH2)6OH suggests that the oligo(ethylene glycol) moieties are effective at preventing underlying methylene groups from influencing wetting by water. A limited study demonstrates that these oligo(ethylene glycol)-containing SAMs resist the adsorption of protein from solution and suggests that SAMs will be a useful model system for studying the adsorption of proteins onto organic surfaces.
