A Chiral Director Field in the Nematic Liquid Crystal Phase Induced by a Poly(.gamma.-benzyl glutamate) Chemical Reaction Alignment Film

Interrelations between charging, structure and electrokinetics of nanometric polyelectrolyte films

“…Applications of polymer-coated substrates include e.g. antimicrobial materials [1], protein-resistant surfaces [2], stimuli-responsive surfaces [3], biosensors [4], liquid displays [5], drug delivery [6] and tissue-engineering scaffolds [7]. The optimization of polymer coatings within the framework of these applications requires refine measurement, analysis and understanding of the physico-chemical properties of the film.…”

On the applicability of the Brinkman equation in soft surface electrokinetics

“…doi:10.1016/j.jcis.2010.04.049 colloidal and biocolloidal systems, e.g., grafted polymers [37], adsorbed biomolecules or polyelectrolyte layers [38], and biological cells [39]. In addition, polymer coatings are used in widespread technological and medical applications like biosensors [40], protein-resistant surfaces [41], tissue engineering scaffolds [42], antifoaming coatings [43], microfluidic systems [44], liquid displays [45], and drug delivery [46]. Appropriate theoretical models are required for the consistent interpretation of experimental results to achieve a quantitative understanding of the electro-hydrodynamic interfacial properties of soft surfaces.…”

Quadrupolar and polar anisotropy in end-grafted α-helical poly(γ-benzyl-L-glutamate) on solid substrates

“…The construction of an ultrathin ␣-helical polypeptide film with a permanent dipole moment is a challenging molecular engineering problem, [1][2][3][4][5][6][7][8][9] with debate focusing on how the dipole moments on a surface would organize themselves leading to an energetically stable structure. [10][11][12] Polypeptides in their ␣-helical form carry a large dipole moment pointing parallel to the helical axis in the direction of the N-terminus.…”
