“…Despite some debate over the incorporation of Tris into polydopamine, it is clear that functionalization with other amines does occur during polymerization of coatings . Compounds with multiple amines such as hexamethylene diamine, partially hydrolyzed poly(2‐methyl‐2‐oxazoline), and polyethyleneimine cross‐link and stabilize catechol‐based coatings to degradation following extended aqueous swelling as well as exposure to strong acids and bases . The incorporation of multiamine compounds into the coatings also influence the surface charge, with the usually negative charge at neutral pH of polydopamine either decreased or converted to a positive zeta potential through polymerization in the presence of diamino compounds and amine rich polymers …”

“…Following this approach, polydopamine and other catecholamines have been modified with various fouling resistant materials and antimicrobial compounds to prevent biofouling of the surfaces . These include hydrophilic antifouling polymers, zwitterionic amino acids, bioinspired antimicrobial compounds, lysing and disinfecting agents, silver nanoparticles, combinations of silver nanoparticles and antifouling polymers, bactericidal enzymes, and the attachment of multidrug eluting polyelectrolyte multilayer coatings …”

“…This includes use as an adhesive layer to immobilize absorbents such as graphene oxide nanosheets, homochiral metal organic frameworks, and gold nanoparticles and alkyl thiols to chromatography columns. Polydopamine has also been exploited as the absorbent when codeposited onto columns with other polymers such as partially hydrolyzed poly(2‐methyl‐2‐oxazoline), polyacrylamide, and polyethyleneimine . Finally, the ampholyte character of polydopamine coatings provides pH variable electro‐osmotic flow, which was employed for the separation of proteins by capillary electrochromatography …”

Almost ten years ago, Lee et al. [13] formulated a universal adhesive coating based on observation of the strong attachment by mussels through their byssal threads to virtually all types of inorganic and organic surfaces. The amino acid compositions of the mussel foot proteins that generate the attachment are rich in catechol and amine groups. [13][14][15] These groups associate under marine conditions, forming strong covalent and noncovalent interactions with substrates. [13] This led to the idea that both catechol and amine groups were crucial in forming robust, wide spectrum adhesive nanolayers [16,17] and consequently dopamine was conceived as a powerful building block for spontaneous deposition of thin polymer films. The dopamine monomer is deposited onto unadulterated surfaces through self-assembly and oxidative cross-linking from mild pH aqueous solution in a rapid reaction. This results in a durable, nanoscale, conformal, and hydrophilic coating that can be readily modified to introduce specific surface chemistries for a particular application. [18][19][20][21][22] These bioinspired, polydopamine materials are chemically and structurally indistinguishable from eumelanins found in the human body, [23,24] providing excellent biocompatibility. Additionally, polydopamine has broad electromagnetic absorption and excellent photothermal energy conversion [25] as well as having ionic-electronic hybrid conductivity. [26] Along with the excellent coating performance, these properties provide a vast array of potential applications for polydopamine materials.In this article, we explain what is known about polydopamine and related catecholamine coatings; their formation, the adhesion mechanism, and their physicochemical properties and we also review the applications of these materials (Figure 1). Since 2011, there have been a number of reviews on this subject matter, including general reviews on the physicochemical properties of polydopamine coatings [11,20,[27][28][29] and their applications. [20,27,30] There are also a number of more specific reviews on the chemical synthesis and modulation of polycatecholamine coatings, [31] the biomedical applications of these coatings, [8,[32][33][34] their electronic properties, [26,35] the use of polydopamine to make films at fluid interfaces, [36] in hierarchically constructed particles, [33] and capsules, [30] exploitation of polycatecholamine coatings in membrane filtration, [37] polydopamine-derived carbon materials, [38] and the use of coordination chemistry in catechol-based materials. [39] Nonetheless, this area of research is growing so rapidly [25,27] that many recent Polydopamine and related polycatecholamines can be easily deposited onto almost any surface from mild, aqueous solution. This results in durable, nanoscale coatings that exhibit high biocompatibility and have useful chemical and electronic properties. Additionally, these materials can be readily chemically and physically modified, and consequently, they are used extensively for surface modification. This ...

“…Thus, diverse polymer termed antifouling coating has emerged for protein analysis [60]. The potential antifouling ability of poly(2-methyl-2-oxazoline) (PMOXA) was investigated by Zhang et al [55] by employing hydrolyzed PMOXA and PDA co-deposition onto the surface of capillary. Basic and acidic proteins were separated using the PDA/partial hydrolyzed PMOXA (PMOXA-EI) coatings.…”

Mussel-inspired polydopamine has been widely used in capillary electrophoresis as a facile and universal tool for the surface modification of capillary, mainly due to its versatility, stability, strong adhesiveness, and biocompatibility properties. In this review, the recent development of mussel-inspired surface chemistry with rapid deposition of polydopamine was introduced, and the recent applications of polydopamine in capillary electrophoresis (2011-July 2018) were summarized into four main aspects, namely, sample pretreatments, functional coatings, codeposition coatings, and intermediate coatings. Further study may be focused on clarifying the mechanisms of polydopamine formation and polydopamine-assisted codeposition, and expanding coatings methods to plant polyphenols.

Recent trends in capillary electrophoresis for complex samples analysis: A reviewCE has been a continuously evolving analytical methodology since its first introduction in the 1980s of the last century. The development of new CE separation procedures, the coupling of these systems to more sensitive and versatile detection systems, and the advances in miniaturization technology have allowed the application of CE to the resolution of new and complex analytical problems, overcoming the traditional disadvantages associated with this method. In the present work, different recent trends in CE and their application to the determination of high complexity samples (as biological fluids, individual cells, etc.) will be reviewed: capillary modification by different types of coatings, microfluidic CE, and online microextraction CE. The main advantages and disadvantages of the different proposed approaches will be discussed with examples of most recent applications.
