Nanopropulsion by biocatalytic self-assembly.
A number of organisms and organelles are capable of self-propulsion at the micro- and nanoscales. Production of simple man-made mimics of biological transportation systems may prove relevant to achieving movement in artificial cells and nano/micronscale robotics that may be of biological and nanotechnological importance. We demonstrate the propulsion of particles based on catalytically controll...
متن کاملPatterned biocatalytic films via one-step self-assembly.
Patterned porous films containing enzymes have been facilely prepared via a one-step breath figure process, which is based on the self-assembly of horseradish peroxidase nanoparticles that show good resistance to organic solvents. The patterned biohybrid films possess robust catalytic activity.
متن کاملSequence Adaptive Peptide-Polysaccharide Nanostructures by Biocatalytic Self-Assembly.
Coassembly of peptides and polysaccharides can give rise to the formation of nanostructures with tunable morphologies. We show that in situ enzymatic exchange of a dipeptide sequence in aromatic peptide amphiphiles/polysaccharide coassemblies enables dynamic formation and degradation of different nanostructures depending on the nature of the polysaccharide present. This is achieved in a one-pot...
متن کاملBiocatalytic Self-Cleaning Polymer Membranes
Polymer membrane surfaces have been equipped with the digestive enzyme trypsin. Enzyme immobilization was performed by electron beam irradiation in aqueous media within a one-step method. Using this method, trypsin was covalently and side-unspecific attached to the membrane surface. Thus, the use of preceding polymer functionalization and the use of toxic solvents or reagents can be avoided. Th...
متن کاملSelf-correcting Information Cascades
We report experimental results from long sequences of decisions in environments that are theoretically prone to severe information cascades. Observed behavior is much different—information cascades are ephemeral. We study the implications of a model based on quantal response equilibrium, in which the observed cascade formation/collapse/formation cycles arise as equilibrium phenomena. Consecutiv...
