Summary: Ultrathin surface-tethered polymer brushes, particularly the zwitterionic poly(carboxybetaine) (pCB) brushes, show great potentials in sensing applications. Experimental studies were conducted to investigate the influence of the alkanethiolate self-assembled monolayers (SAMs) chain length on the properties of the antifouling poly(carboxybetaine methacrylamide) (pCBMAA) brushes. The results showed that the SAM length has a significant impact on the characteristics of the brushes, with longer-chain SAMs exhibiting better biofouling resistance.

Summary: Bis[2-(2-bromoisobutyryloxy) undecyl] disulphide (DTBU) is an initiator for surface-initiated atom transfer radical polymerization (SI-ATRP) that can functionalize metal surfaces through formation of self-assembled monolayers (SAM). This article characterizes the DTBU initiator monolayers on gold polycrystalline electrodes using electrochemical methods such as cyclic voltammetry, capacity-potential curves, electrochemical impedance spectroscopy, and angle contact measurements. The monolayers' integrity and permeability are determined through capacitance potential measurements and impedance spectra. Furthermore, the effect of SAM as a physical barrier on different redox probes is explored. The study also examines mixed monolayers of DTBU and 6-mercaptopurine for their potential use in electron exchange through monolayers.
