recommendations! Published in 2020 at "Analytical and Bioanalytical Chemistry"

DOI: 10.1007/s00216-020-02607-7

Abstract: Though the advances in microelectronic device fabrication have realized new capabilities in integrated analytical and diagnostic platforms, there are still notable limitations in point-of-care sample preparation. AC electrokinetic devices, especially those leveraging dielectrophoresis (DEP), have… read more here.

DOI: 10.1016/j.jelechem.2017.10.023

Abstract: Abstract The adsorption and oxidation of squaric acid (3,4-dihydroxycyclobut-3-ene-1,2-dione, H 2 C 4 O 4 , SQA) at platinum and gold electrodes were studied spectroelectrochemically in perchloric acid solutions. Voltammetric experiments demonstrate that reversible adsorption… read more here.

DOI: 10.1126/science.362.6413.416-b

Abstract: Electrochemistry Platinum (Pt) electrodes can undergo oxidation and reduction that can alter their surface morphology. Deng et al. used atomic force microscopy to follow changes in surface morphology of a smooth Pt foil in sulfuric… read more here.
