In vitro antibacterial capacity and cytocompatibility of SiO-CaO-PO meso-macroporous glass scaffolds enriched with ZnO.

Zn ions exhibit osteogenic, angiogenic and antimicrobial properties. For this reason, they are often added in small amounts to bioceramics being investigated for bone tissue engineering. In this paper, the cytocompatibility and antibacterial properties of 80% SiO-15% CaO-5% PO (mol%) mesoporous bioactive glass (MBG) scaffolds substituted with 4.

Analysis and design of hybrid ARROW-B plasmonic waveguides.

A hybrid antiresonant reflecting waveguide, type B (ARROW-B) plasmonic waveguide based on the resonant coupling between a guided dielectric mode and surface plasmon polariton wave is proposed. Employing the finite element method, hybrid modes including two bound supermodes are obtained at visible frequencies by varying the environmental refractive index. We investigate the propagation characteristics of hybrid modes, where the significant change of modal power by the symmetric bound mode is observed in plasmonic waveguide coupling suitable for highly sensitive detection of bulk refractive index change.
