Carrier systems and biosensors for biomedical applications.

Davis, Frank; Higson, Seamus P. J. (2007-10-31)

This chapter addresses both carrier systems and biosensors which are often applied directly to tissues, either as skin patches, implanted or ingested by a variety of routes. It follows that there is a common theme between ...
The electrochemistry of the ferri/ferrocyanide couple at a calix [4]resorcinarenetetrathiol-modified gold electrode as a study of novel electrode modifying coatings for use within electro-analytical sensors

Collyer, Stuart D.; Davis, Frank; Lucke, Andrew; Stirling, Charles J. M.; Higson, Seamus P. J. (Elsevier Science B.V., Amsterdam., 2003-06-05)

The electrochemistry of the ferri/ferrocyanide redox couple has been studied at Au electrodes modified with calix[4]resorcinarenetetrathiol. Cyclic voltammetry in Fe(CN)63- solutions yields three separate pairs of faradaic ...
Labeless AC impedimetric antibody-based sensors with pg ml-1 sensitivities for point-of-care biomedical applications.

Barton, Andrew C.; Collyer, Stuart D.; Davis, Frank; Garifallou, Goulielmos-Zois; Tsekenis, Georgios; Tully, Elizabeth; O'Kennedy, Richard; Gibson, Tim; Millner, Paul A.; Higson, Seamus P. J. (Elsevier Science B.V., Amsterdam., 2009-01-01)

This paper describes the development and characterisation of labeless immunosensors for (a) the cardiac drug digoxin and (b) bovine serum albumin (BSA). Commercial screen-printed carbon electrodes were used as the basis ...
Labeless and reversible immunosensor assay based upon an electrochemical current-transient protocol

Grant, Sarah; Davis, Frank; Pritchard, Jeanette A.; Law, Karen A.; Higson, Seamus P. J.; Gibson, Timothy D. (Elsevier Science B.V., Amsterdam., 2003-10-24)

A novel labeless and reversible immunoassay based upon an electrochemical current-transient protocol is reported which offers many advantages in comparison to classical immuno-biochemical analyses in terms of simplicity, speed ...
Langmuir and LB properties of two calix[4]resorcinarenes: Interactions with various analytes

Sugden, Mark W.; Richardson, Tim H.; Davis, Frank; Higson, Seamus P. J.; Faul, Charl F. J. (Elsevier Science B.V., Amsterdam., 2008-05-15)

The ability of calixarene-based molecules to interact with amino acids has been the basis of many studies. The Langmuir and LB properties of two calix [4]resorcinarenes have been investigated. The properties of the layer ...
New Techniques in Monitoring Water Pollution - Development of Sonochemically Fabricated Microarrays for the Determination of Pollutants.

Davis, Frank; Collyer, Stuart D.; Gornall, Davinia D.; Law, Karen A.; Mills, Daniel W.; Higson, Seamus P. J. (Teknoscienze Srl, 2007-01-01)

The focus of this article is to describe a simple-to-use, disposable sensor suitable for the rapid determination of pollutants in aqueous media, utilising a novel sonochemical microelectrode fabrication technique. The ...
Optical and AFM study of electrostatically assembled films of CdS and ZnS colloid nanoparticles.

Suryajaya, S.; Nabok, Alexei; Davis, Frank; Hassan, A.; Higson, Seamus P. J.; Evans-Freeman, J. (Elsevier Science B.V., Amsterdam., 2008-05-30)

CdS and ZnS semiconducting colloid nanoparticles coated with the organic shell, containing either SO3− or NH2+ groups, were prepared using the aqueous phase synthesis. The multilayer films of CdS (or ZnS) were deposited ...
Polymers in biosensors.

Davis, Frank; Higson, Seamus P. J. (2007-08-06)

This chapter will be devoted to the incorporation of polymers within biosensors, beginning with a history and descriptions of basic sensor formats - while concentrating on optical and electrochemical sensors. Initially ...
Sonochemically fabricated microelectrode arrays for biosensors offering widespread applicability. Part I

Barton, Andrew C.; Collyer, Stuart D.; Davis, Frank; Gornall, Davinia D.; Law, Karen A.; Lawrence, Emma C. D.; Mills, Daniel W.; Myler, Suzy; Pritchard, Jeanette A.; Thompson, Mark; Higson, Seamus P. J. (Elsevier Science B.V., Amsterdam., 2004-09-15)

A novel and patented procedure is described for the sonochemical fabrication of a new class of microelectrode array based sensor with electrode element populations of up to 2 x 105 cm-2. For some years it has been accepted ...
Sonochemically fabricated microelectrode arrays for biosensors. Part II. Modification with a polysiloxane coating

Myler, Suzy; Davis, Frank; Collyer, Stuart D.; Higson, Seamus P. J. (Elsevier Science B.V., Amsterdam., 2004-09-15)

A polymer modified sonochemically fabricated glucose oxidase microelectrode array with microelectrode population densities of up to 2.5 x 105 microelectrodes cm-2 is reported. These microelectrode sensors were formed ...
The study of genomic DNA adsorption and subsequent interactions using total internal reflection ellipsometry.

Nabok, Alexei; Tsargorodskaya, Anna; Davis, Frank; Higson, Seamus P. J. (Elsevier Science B.V., Amsterdam., 2007-10-31)

The adsorption of genomic DNA and subsequent interactions between adsorbed and solvated DNA was studied using a novel sensitive optical method of total internal reflection ellipsometry (TIRE), which combines spectrosco ...
Ultra-Sensitive determination of pesticides via cholinesterase-based sensors for environmental analysis.

Davis, Frank; Law, Karen A.; Chaniotakis, Nikos A.; Fournier, Didier; Gibson, Timothy D.; Millner, Paul A.; Marty, Jean-Louis; Sheehan, Michelle A.; Ogurtsov, Vladimir I.; Johnson, Graham; Griffiths, John; Turner, Anthony P. F.; Higson, Seamus P. J. (Elsevier, 2007)

This review is focussed towards the development of acetylcholinesterase enzymatic based biosensors for the quantification of trace concentrations of highly toxic pesticides via their inhibitory effect on the enzyme. Initial ...
