A high curvature flexible Bragg grating, in planar technology, is designed, fabricated and experimentally characterized by employing silica glass. The sensing mechanism for slightly off-axis core theoretically explained demonstrated. electromagnetic behavior of the proposed sensor investigated through conformal mapping, modal analysis, coupled-mode theory. experimental measurement reveals diffe...

Star polymers containing one central core surrounded by multiple radiating arms represent an intriguing type of globular platform to be used as unimolecular containers and reactors. The core domain can encapsulate guest "cargos", whereas protective shell and chain ends can be functionalized with reactive groups and ligands. This Feature Article highlights the recent development on using core-sh...

AIM In order to improve the delivery of aromatic drugs by micellar assemblies, and particularly by long and flexible filomicelles, aromatic groups were integrated into the hydrophobic block of a degradable diblock copolymer. MATERIALS & METHODS Aromatic filomicelles were formed by self-directed assembly of amphiphilic diblock copolymer PEG-PBCL with suitable block ratios. Worm-like filomicell...
