This thiol is useful in a wide range of applications. Aizenberg and co-workers used SO3- terminated SAMs to control shape, size and morphology of calcite microcrystals (Mater. Res. Soc. Symp. Proc.823, 115-119, 2004; Nature398, 495-498, 1999). The Whitesides group used it to study redox properties of SAM-adsorbed Cytochrome c (Langmuir18, 7009-7015, 2002), while Lin and Chuang investigated its high reactivity towards blood platelets (J. Biomed. Mater. Res. 51, 413-423, 2000). The highly charged sulfonic acid monolayer was also found suitable for electrodeposition of thin polyaniline films (J. Am. Chem. Soc. 120, 10733-10742, 1998) and - in disordered state - served as a molecular sieve selectively permeable to electroactive species (Proc. Electrochem. Soc. 271-277, 1997). Yet another unique thiol from ProChimia.
