  • Photochemical polymerization of thiophene derivatives in aqueous solution 
    Piletsky, Sergey A.; Piletska, Elena V.; Karim, K.; Davis, Frank; Higson, Seamus P. J.; Turner, Anthony P. F. (Royal Society of Chemistry, 2004-08-20)
    A novel method of photochemical polymerization of thiophene derivatives in aqueous solution catalyzed by potassium dichromate and initiated by illumination is described.
  • 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 ...
  • Procedure 24 : Construction of an enzyme-containing microelectrode array and use for detection of low levels of pesticides 
    Davis, Frank; Law, Karen A.; Turner, Anthony P. F.; Higson, Seamus P. J. (2007-01-01)
    Objectives (a) To construct a microelectrode array based on a screen printed substrate. (b) To utilise the microelectrode array to form an array of enzyme- containing electrodes (c) To test the electrode response to ...
  • Sol-gel based sensor for selective formaldehyde determination 
    Bunkoed, Opas; Davis, Frank; Kanatharana, Proespichaya; Thavarungkul, Panote; Higson, Seamus P. J. (Elsevier Science B.V., Amsterdam., 2010-02-01)
    We report the development of transparent sol–gels with entrapped sensitive and selective reagents for the detection of formaldehyde. The sampling method is based on the adsorption of formaldehyde from the air and reaction ...
  • 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 ...
  • Species differentiation by DNA-modified carbon electrodes using an ac impedimetric approach. 
    Davis, Frank; Nabok, Alexei; Higson, Seamus P. J. (Elsevier Science B.V., Amsterdam., 2005-02-15)
    A simple and novel electrochemical biosensor based approach is described for differentiating between differing species of fish on the basis of DNA hybridisation events. Screen-printed carbon electrodes modified with a ...
  • 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 ...
  • Volatile organic compounds sensing using optical fibre long period grating with mesoporous nano-scale coating 
    Hromadka, J.; Korposh, Sergiy; Partridge, Matthew; James, Stephen W.; Davis, Frank; Crump, Derrick; Tatam, Ralph P. (MDPI, 2017-02-08)
    A long period grating (LPG) modified with a mesoporous film infused with a calixarene as a functional compound was employed for the detection of individual volatile organic compounds (VOCs) and their mixtures. The mesoporous ...
