“…Furthermore, the order and coverage of the molecules in the modification layer is also dependent on both the molecules to be used and the surface. This has been illustrated by McCreery and coworkers [90] where the diazonium salt of nitroazobenzene gave well ordered monolayers on glassy carbon but not on the basal places of HOPG or diamond where the coverage was only between 50 to 70% of a monolayer [91]. Furthermore, the reaction in Scheme 1 is only the dominant reaction as side reactions do occur; the nature of which depends on the R group and the surface being modified.…”

A high degree of control over the modification of electrode surfaces is required for many sensing applications. This critical review briefly outlines some of the considerations for interfacial design in amperometric sensors and discusses some of advantages and disadvantages of alkanethiol modified metal electrodes for such applications before concentrating on the modification of electrodes surfaces using aryl diazonium salts. The pros and cons of this chemistry, and the application of aryl diazonium salts for sensing on carbon electrodes is reviewed before recent advances in using this chemistry for modifying metal electrodes are presented.

“…Electrochemically modified diamond surfaces Kuo et al introduced aromatic groups onto the surface of B-doped diamond by the electrochemical reduction of phenyl diazonium salts on the surface [64]. Diamond powders exposed to NO 2 near RT were found to have stably adsorbed RNOx and ROx species (in which R stands for radical) on the surface by Azambre et al [65].…”

This article reviews the current state‐of‐the art of diamond‐based DNA sensors. Some general concepts involved in biosensors are introduced and applied to DNA sensors. The properties of chemically vapor deposited (CVD) diamond relevant for this application are summed up, with special attention for the stability and bio‐compatibility of the material. Several routes to functionalize the diamond surface are considered. The physical properties of the obtained DNA layers are discussed in terms of surface density and molecular conformation. Possible read‐out strategies are evaluated, including optical and electronic sensing. With diamond‐based DNA sensors, real‐time and label‐free sensing is achieved. (© 2009 WILEY‐VCH Verlag GmbH & Co.

“…The order and coverage of the modifier molecules in the modification layer also depends on the type of modifier as well as the substrate surface. This has been illustrated by McCreery and co-workers [20] where the diazonium salt of nitroazobenzene gave well ordered monolayers on glassy carbon but not on the basal planes of HOPG or diamond where the coverage was only between 50 -70% of a monolayer [21].
