Nanostructured Polymer Brushes

Small, 2007
AbstractNanopatterned polymer brushes with sub‐50‐nm resolution were prepared by a combination of electron‐beam chemical lithography (EBCL) of self‐assembled monolayers (SAMs) and surface‐initiated photopolymerization (SIPP). As a further development of our previous work, selective EBCL was performed with a highly focused electron beam and not via a ...

BRONCHIAL BRUSH BIOPSY WITH A CONTROLLABLE BRUSH

American Journal of Roentgenology, 1970
A controllable brush and a new controllable guide wire have been developed for selective bronchial catheterization and bronchial brush biopsy. The technique for using these instruments is described.This system offers 2 principal advantages over previous methods: it decreases the average time required for the examination; and it extends the range of the

Molecular Bottlebrushes Featuring Brush-on-Brush Architecture

ACS Macro Letters, 2019
Molecular bottlebrushes featuring brush-on-brush (BoB) architecture were prepared by combining azide-alkyne click chemistry, ring-opening polymerization (ROP), and atom transfer radical polymerization (ATRP). Primary side chains of diblock copolymers with a poly(ε-caprolactone) (PCL) block and a poly(α-bromo-ε-caprolactone) (P(CL-Br)) block were ...
