An Enzyme-Responsive Controlled Release Drug Delivery System Based on Mesoporous Silica and DNA

Zhang X., Wu Z., Hefei Institutes of Physical Science, Chinese Academy of Sciences, CN

An efficient enzyme-responsive controlled release drug delivery system was fabricated using functional mesoporous silica nanoparticles (FMSN) encapsulated with the single-stranded DNA. Based on the electrostatic interactions between FMSN and single-stranded DNA, the DNA coating could [...]

Multi-functionalizations of Mesoporous Hollow Silica Nanospheres and Their HIFU Application

Chen H., Chen Y., Zhang K., Wang X., Chen H., Chen Y., Shi J., Shanghai Institute of Ceramics, CN

High intensity focused ultrasound (HIFU), as a representative non-invasive therapeutic mode, has attracted extensive attentions among biological and medical researchers. In this report, we focused on constructing novel mesoporous hollow silica nanospheres (MHSNs) as innovative [...]

Multi-functional silica microdot arrays by inkjet printing for biosensor applications

De Los Cobos O., Lejeune M., Rossignol F., Carrion C., Boissière C., Ribot F., Sanchez C., Cattoën X., Wong Chi Man M., Durand J.-O., SPCTS, FR

Silica-based microarrays for molecular recognition are realized using a piezoelectric drop-on-demand inkjet printer. A sol containing tetraethyl orthosilicate (TEOS) and (3-azidopropyl)triethoxysilane is used as ink to print azido-functionalized mesoporous silica microdots arrays clickable with various [...]

Silylation Hardening for Mesoporous Silica Zeolite Film

Kikkawa T., Hiroshima University, JP

Pure silica zeolite films were prepared for ultra-low-k interlayer dielectrics in ultra-large integrated circuits by both hydrothermal crystallization using tertabuthylammonium hydroxide, tetraethylorthosilicate and ethylalcohol, and vapor phase transport synthesis using ethylene diamine and triethylamine. Self-assembled [...]

Growth of Carbon Nano-Structures in Ceramic Materials

Kufazvinei C., Leahy R.W., Lipson S.M., Blau W.J., Dillon F.C., Spalding T.R., Morris M.A., Holmes J.D., Allan G., Patterson J., Trinity College Dublin, IE

The investigation aims at growing carbon nanotubes of controlled diameter from inside pores of ceramic materials. The resulting carbon nanotubes will then be used in electrons as thermally conductive substrates in die mountings.
