“…At present, 4 enzyme classes, oxidoreductases, transferases, hydrolases and ligases, are identified to induce or catalyze polymerizations ( Table 3 ) [ 200 ]. Many polymers are successfully synthesized via enzymatic polymerizations, for example, vinyl polymers [ 38 , 201 ], polysaccharides [ 202 , 203 , 204 , 205 ], polyesters [ 42 , 44 ] and polyamides [ 206 , 207 , 208 ]. Among them, polyesters are the most extensively studied polymers in enzymatic polymerization; and lipases are the most efficient biocatalysts for enzymatic polymerization of polyesters [ 42 ].…”

Nowadays, "green" is a hot topic almost everywhere, from retailers to universities to industries; and achieving a green status has become a universal aim. However, polymers are commonly considered not to be "green", being associated with massive energy consumption and severe pollution problems (for example, the "Plastic Soup") as a public stereotype. To achieve green polymers, three elements should be entailed: (1) green raw materials, catalysts and solvents; (2) eco-friendly synthesis processes; and (3) sustainable polymers with a low carbon footprint, for example, (bio)degradable polymers or polymers which can be recycled or disposed with a gentle environmental impact. By utilizing biobased monomers in enzymatic polymerizations, many advantageous green aspects can be fulfilled. For example, biobased monomers and enzyme catalysts are renewable materials that are derived from biomass feedstocks; enzymatic polymerizations are clean and energy saving processes; and no toxic residuals contaminate the final products. Therefore, synthesis of renewable polymers via enzymatic polymerizations of biobased monomers provides an opportunity for achieving green polymers and a future sustainable polymer industry, which will eventually play an essential role for realizing and maintaining a biobased and sustainable society.

“…17 In addition, enzymes are also nontoxic; they are obtained from natural renewable resources and can often be recycled. 17 Especially enzymes from the classes of glycosyl transferases and hydrolases (EC 2.4 and 3.2) 18 have been used in organic synthesis of ( poly)saccharides and glycosides since carbohydrates are their natural substrates. α-Amylases have been applied as catalysts in the organic synthesis of glycosides of various alcohols (methyl-, ethyl-, propyl-, butyland benzyl-).…”

“…Enzymatic synthesis methods are very attractive for their mild reaction conditions, for the high enantio‐, regio‐ and chemoselectivity as well as for the nontoxicity of natural catalysts . In enzymatic methods for glycoside and saccharide synthesis no selective protection/deprotection steps are necessary and the control of configuration at newly formed anomeric centers is absolute …”

“…[21][22][23][24] In enzymatic methods for glycoside and saccharide synthesis no selective protection/deprotection steps are necessary and the control of configuration at newly formed anomeric centers is absolute. [25][26][27][28][29] Interestingly, the first surface-initiated enzymatic polymerization ever reported was the synthesis of amylose brushes on planar and spherical surfaces [30,31] and this approach was extended recently by the synthesis of amylopectin brushes via an enzymatic ''grafting from'' procedure. [32] However, to date a proper surface chemistry characterization of these systems is still missing.…”

The successful synthesis of amylose brushes via enzymatic "grafting from" polymerization and the detailed characterization of all synthetic steps by X-ray photoelectron spectroscopy (XPS) and spectroscopic ellipsometry measurements are reported. Au and Si surfaces are amino-functionalized with self-assembled monolayers (SAMs) of cystamine and 3-aminopropyldimethyethoxysilane (APDMES), respectively. Maltoheptaose is covalently attached to the amino-functionalized Au and Si surfaces via reductive amination. Amylose brushes are grown from maltoheptaose modified Au and Si surfaces with enzymatic polymerization using potato phosphorylase and Rabbit Muscle phosphorylase, as evidenced by spectroscopic ellipsometry and XPS measurements.
