Self-assembled architectures from biohybrid triblock copolymers.
The synthesis and self-assembly behavior of biohybrid ABC triblock copolymers consisting of a synthetic diblock, polystyrene-b-polyethylene glycol (PSm-b-PEG113), where m is varied, and a hemeprotein, myoglobin (Mb) or horse radish peroxidase (HRP), is described. The synthetic diblock copolymer is first functionalized with the heme cofactor and subsequently reconstituted with the apoprotein or ...
متن کاملElastic properties of polymer interfaces: aggregation of pure diblock, mixed diblock, and triblock copolymers.
Block copolymers adsorbing to an interface between two immiscible homopolymers modify the elastic constants of this interface. Within self-consistent field calculations for Gaussian chains, we determine how the bending constants vary in dependence on the block copolymer concentration and architecture. Four phenomena are discussed. (i) When a tricritical or isotropic Lifshitz critical point is a...
متن کاملNanoscale protein patterning using self-assembled diblock copolymers.
Novel methods for immobilizing proteins on surfaces have the potential to impact basic biological research as well as various biochip applications. Here, we demonstrate a unique method to pattern proteins with a nanometer periodicity on silicon oxide substrates using microphase-separated diblock copolymer thin films. We developed a straightforward and effective protein immobilization technique ...
متن کاملElastic Properties and Line Tension of Self-Assembled Bilayer Membranes ELASTIC PROPERTIES AND LINE TENSION OF SELF-ASSEMBLED BILAYER MEMBRANES
The bending moduli and line tension of bilayer membranes self-assembled from diblock copolymers was calculated using the self-consistent field theory. The limitation of the linear elasticity theory (Helfrich model) was evaluated by calculating fourthorder curvature moduli in high curvature systems. It was found that in highly curved membranes, the fourth-order contributions to the bending energ...
متن کاملPatchy nanoparticles self-assembled from linear triblock copolymers under spherical confinement: a simulated annealing study.
The self-assembly of linear ABC triblock copolymers confined in spherical nanopores is studied using a simulated annealing technique. Morphological phase diagrams as a function of the pore diameter, the selectivity of the pore-wall to the terminal blocks, and the copolymer composition are constructed. A variety of patchy nanoparticles and multiple morphological transitions are identified. Janus...
