The interaction of ferrocene‐boronic acid with fructose is investigated in aqueous 0.1 m phosphate buffer at pH 7, 8 and 9. Two voltammetric methods, based on 1) a dual‐plate generator–collector micro‐trench electrode (steady state) and 2) a square‐wave voltammetry (transient) method, are applied and compared in terms of mechanistic resolution. A combination of experimental data is employed to obtain new insights into the binding rates and the cumulative binding constants for both the reduced ferrocene‐boronic acid (pH dependent and weakly binding) and for the oxidised ferrocene‐boronic acid (pH independent and strongly binding).

“…Microelectrode techniques have been applied to kinetics of electron transfer reactions either in rapid scan voltammetry [1][2][3] or in steady-state voltammetry [2][3][4][5][6][7][8][9][10][11][12][13]. An advantage of the former is due to minimizing potential drop by a solution resistance because of small current values [14].…”

“…Thus it is interesting to combine fast scan voltammetry with steady-state microelectrode voltammetry [2]. In order to obtain consistent data between two kinds of voltammetry, a well-known redox couple with a sluggish reaction rate should be chosen.…”

“…52 Ghisla et al 8 and Mattevi et al 53 have proposed that the protein substrate is oxidized by direct hydride transfer to the flavin N5, and the proper positioning of the substrate and the reactive flavin N5 atom is essential. 54 Another example of a nucleophilic addition to the flavin N5 position is in fungal nitroalkane oxidase. The -proton of the nitroalkane is abstracted, and the resultant carbanion attacks the flavin N5 position to form a covalent adduct with the flavin, generating a cation flavin imine.…”

A thesis submitted to the Nanyang Technological University in fulfillment of the requirements for the degree of Doctor of Philosophy of Chemistry First and foremost, I would like to thank Nanyang Technological University (NTU) for awarding me the Nanyang President's Graduate Scholarship, and giving me opportunities to attending 2 conferences which has broadened my horizons both scientifically and personally. I would also like to thank my PhD supervisor, Assoc. Prof. Richard David Webster, for accepting me into his group without prior experience, for providing guidance over these 4 years, for giving me space and freedom to explore the field, for understanding, for never having any harsh words and being really great to talk to even for non-electrochemistry topics. Much love to my lunch buddies, Gwen, Shu Jun, Novi, for being the best part of these 4 years, making me look forward to school every day. Also, I am really thankful to my student Jiamin, for being so reliable, meticulous and determined. I could not have done it without you, and could not have asked for a better student! To all Gwen's ex-students and my ex-lunch buddies (Marcus, Shu Jun, Li Zhen, Li Lin and Wen Hui), it has been great knowing all of you! Special thanks to Shu Jun and Novi for the last few months, starving yourselves till 2 pm to lunch with me, to Novi for stepping up without complaints to help me with data collection, to Yanni for always being so kind and sweet, and to Diane for understanding! Also, thanks to Shu Hui for our dinners, for working late together and for the trips home. To Colin, thanks for your friendship and "thanks" for scaring me while making sure I am not holding any glassware. To Weejian, thanks for your kind notes of encouragement during my FYP days, and being the kind of friend that sticks around. To Boon Hong, thanks for being mature and understanding, for helping me with ithenticate II and so much more, you are truly a much better person than you are given credit for! You are friends I wish I knew earlier and hope to keep for many years to come! To my other labmates,
