Mercaptopropionic linker

Figure 8-10. Overview of small linker molecules recently characterized to molecular resolution by in situ STM on Au(lll)-electrode surfaces in aqueous buffer under potential control. A Bare reconstructed Au(l 11 )-surface. B (2 3 xV3)R30°-4 butanethiol monolayer (hydrophobic). C (2 3 x 6)R30°-6 monolayer of mercaptopropionic acid (negatively charged).D (V3 x 4)R30°-2 monolayer of cysteamine (positively charged). E (3 3 x 6)R30°-6 monolayer of cysteine/cystine (zwitterionic). ...

PAM AMs [poly(amidoamine) dendrimers] are commercially available hyperbranched cores. T-antigen [Thomsen-Friedenreich, [3-Gal-(l,3)-oc-D-GalNAc-OR, 29] was successfully attached to PAMAM 30 via a 3-(propyl)mercaptopropionic acid linker to investigate T-antigen-protein interactions [44] (Scheme 20.8). 

Nanostructured electrodes of wide band gap semiconductors can be coated with QDs by a number of methods direct adsorption of QDs on nanostructured semiconductor networks can be achieved by CBD, electrodeposition or spin coating. Alternatively, they can be anchored using linkers, such as mercaptopropionic acid (MPA), which have an acid function which binds to metal oxides, such as Ti02 and ZnO, and a thiol (or amine) group, which binds to CdSe or CdS. When linkers such as MPA are used, a uniform coverage throughout the internal and external...
