“…Because the backbone of the graft copolymer is made from methacrylic monomers, as a first approximation, we used in our estimations the parameters known for methyl methacrylate (Supporting Information: S3). N determined experimentally from the DLS experiments is close to the weight-average value; therefore, we used weight-average N in the calculations. It was found that ⟨ R 2 ⟩ 1/2 and ⟨ R g 2 ⟩ 1/2 are equal to 29 and 12 nm, respectively.…”

Surface modification with polymer grafting is a versatile tool for tuning the surface properties of a wide variety of materials. From a practical point of view, such a process should be readily scalable and transferable between different substrates and consist of as least number of steps as possible. To this end, a cross-linkable amphiphilic copolymer system that is able to bind covalently to surfaces and form permanently attached networks via a one-step procedure is reported here. This system consists of brushlike copolymers (molecular brushes) made of glycidyl methacrylate, poly(oligo(ethylene glycol) methyl ether methacrylate), and lauryl methacrylate, which provide the final product with tunable reactivity and balance between hydrophilicity and hydrophobicity. The detailed study of the copolymer synthesis and properties has been carried out to establish the most efficient pathway to design and tailor this amphiphilic molecular brush system for specific applications. As an example of the applications, we showed the ability to control the deposition of graphene oxide (GO) sheets on both hydrophilic and hydrophobic surfaces using GO modified with the molecular brushes. Also, the capability to tune the osteoblast cell adhesion with the copolymer-based coatings was demonstrated.

“…Nanocrystalline cellulose (NCC) (CelluForce Inc., Montreal, CAN) was prepared as a 0.5% (w/v) solution in ultrapure water. The molecular weight of NCC was determined through dynamic light scattering 19 The mean molecular weight (87.1 kDa) was used to calculate the concentration of the solution (Debye Plot, Supporting Information Figure S1). The NCC solution was diluted in 15 consecutive 1:2 dilution steps to give final volumes of 31.5 μL.…”

Carbohydrate-binding modules (CBM) have emerged as useful tools for a wide range of tasks, including the use as purification tags or for cellulose fiber modification. For this purpose, the CBM needs to be attached to a target protein leading to large constructs. We investigated if short peptides from the carbohydrate binding site of CBMs can bind in a similar way as native, full-length CBMs to nanocrystalline cellulose (NCC) or cotton linter paper. We designed our cellulose-binding peptides to be less hydrophobic and shorter than those previously reported. Starting from the binding site of Cel7A-CBM1, we incorporated the essential amino acids involved in cellulose binding into our peptides. These peptides, as well as control peptides with scrambled sequences or a lack of essential amino acids, bound to cellulose with similar affinity as CBM regardless of their secondary structure, sequence, or hydrophobicity. This unspecific mode of cellulose binding displayed by the presented peptides may be exploited to functionalize cellulose-based biomaterials by means of peptide-conjugates.
