Using Self-Polymerized Dopamine to Modify the Antifouling Property of Oligo(ethylene glycol) Self-Assembled Monolayers and Its Application in Cell Patterning

Abstract

We report a one-step, mild method to modify antifouling oligo(ethylene glycol)-terminated self-assembled monolayers. We demonstrate for the first time that self-polymerized dopamine, previously reported as an underwater adhesive, can be patterned on typical antifouling surfaces by microfluidic patterning or microcontact printing. The patterns can be applied in spatiotemporal cell patterning.

Polydopamine-Assisted Surface Modification for Bone Biosubstitutes

“…The immobilization of rabbit chondrocytes has been improved with the formation of PDA coating layer on biosubstitutes as compared to unmodified surface. Additionally, the PDA coated surface can enhance the attachment of NT3T3 fibroblast cell [73, 74]. The amine-(thiol-) terminated methoxy-poly(ethylene glycol) (mPEG-SH/mPEG-NH 2 ) with PDA coating layer can improve the cell adhesion behavior although this biosubstitute material exhibits an adverse effect of inhibiting the growth of NIH 3T3 cells [29].…”

Immobilization of epidermal growth factor on titanium and stainless steel surfaces via dopamine treatment

“…This reaction is considered as the formation of a dopamine-melanin layer on the surface [46,47]. These treatments provide not only organic layers but also further immobilization of biological molecules on the surface of various materials [48][49][50][51][52][53][54][55][56][57][58][59][60][61][62].…”

Tuning photoluminescence properties of ZnO nanorods via surface modification

“…A tight, adherent polydopamine (pDA) layer can be formed on the substrate surface due to the polymerization after it is immersed in the dopamine solution for a certain period of time. Hence, dopamine and its derivatives can be used for the modification of various materials for some specific applications, like stabilizing nanomaterials [19], altering surface wettability [20], increasing corrosion resistance [21], and modifying the antifouling property [22]. In this work, the dopamine was used to modify ZnO nanorod arrays via a simple assembly method.…”
