“…Arevalo et al [135] have recently reported a sensitive adsorptive stripping SWV method for detection of the steroid progesterone on a glassy carbon electrode. The authors of the latter work also paid attention on the adsorption of progesterone on the working electrode surface, while evaluating thermodynamic parameters of the adsorption strength.…”

“…A plethora of intriguing studies has been conducted in relation to the kinetics of charge transfer processes at liquid/liquid interfaces [18][19][20][21][22][23], electrochemistry of immobilized proteins [24,25], and catalytic mechanisms [26][27][28], revealing that SWV is highly suited for both mechanistic and kinetic characterization of electrode reactions, besides its excellent analytical performances [29][30][31][32][33][34] and its appropriateness for bioanalytical applications [35][36][37][38][39][40][41].…”

The kinetics of surface confined electrode reactions of alizarin, vitamin B12, and vitamin K2 is measured with square‐wave voltammetry over a wide pH interval, by applying the recent methodology for kinetic analysis at a constant scan rate [V. Mirceski, D. Guziejewski, K. Lisichkov, Electrochim. Acta 2013, 114, 667–673]. The reliability and the simplicity of the recent methodology is confirmed. The methodology requires analysis of the peak potential separation of the forward and backward component of the response as a function of the pulse height (SW amplitude), for a given frequency (i.e. constant scan rate) of the potential modulation.

“…Progesterone is a natural steroid and an essential hormone for stabilization and maintaining pregnancy. In mammals it is formed from cholesterol, primarily in ovaries, placenta, and the adrenal glands where it is synthesized after ovulation [1,2,3,4,5]. In addition, progesterone is a precursor of other essential hormones (estrogen, testosterone) in the adrenal glands, influencing their activity [6].…”

“…In clinical diagnostics, several detection methods were developed for detecting progesterone, including spectroscopic, spectrometric (hyphenated with chromatography), enzymatic immunoassay, etc [13,14,15,16]. More recently, several examples of electrochemical immunoassay emerged, together with a few cases of direct voltammetric detection performed on mercury, tin and various carbon electrodes in alkaline media [3,4,17,18,19,20].…”

Progesterone is an important hormone responsible, among others, for maintaining pregnancy via inhibition of uterus muscles activity; thus, following its concentration levels in pregnant women is of immense importance in the endeavor to prevent premature birth. In this work, the nanostructured bismuth film electrode (nsBiFE) was studied for detection of progesterone in neutral medium. Due to the ability to accumulate progesterone at the nsBiFE, the adsorptive cathodic stripping voltammetry was beneficially exploited. The nsBiFE was prepared on the surface of a glassy carbon supporting electrode and several parameters influencing the detection of progesterone were investigated. The nsBiFE exhibited superior electroanalytical characteristics in comparison to other bismuth-based electrodes and unmodified glassy carbon electrode together with satisfactory response toward low concentrations of progesterone, which are consistent with clinically significant levels.
