    报告简介:

    This talk will explore the application of nanostructured silicon including porous silicon and silicon nanowires in drug and gene delivery, optical and electrochemical biosensors and in regenerative medicine. These elemental silicon-based materials have high surface area of up to several hundreds of square meters per gram, facilitating loading of considerable amounts of bioactives. Second, pore size can be tailored over a wide range, spanning from the nano- to the microscale. Being able to 'dial in' a certain pore size allows for facile optimisation of topographical cues for attachment, guidance, proliferation and differentiation of target cells. At the same time, the rate of diffusive release of drugs can be tuned by adjusting the pore size. Third, the materials are biocompatible and biodegradable, with the nanostructured elemental silicon undergoing oxidative hydrolysis in aqueous medium at a rate that is easily tunable by means of the surface chemistry from hours to months. A diverse range of surface chemistries is available for this material, some of which are amenable to surface patterning, formation of surface-bound gradients and formation of silicon-polymer hybrid materials. Finally, thin films, membranes and particles of porous silicon display interferometric reflectance and photonic effects, which are responsive to binding of target biomolecules. This talk will first introduce nanostructured silicon material properties and fabrication and characterisation aspects, including describing strategies for nano- and microscale patterning and gradient formation. This will be followed by an overview of the work using porous silicon nanostructured films as optical and electrochemical transducers. Drug delivery applications for targeted cancer therapy, immunotherapy and the therapy of ocular diseases will be highlighted, and the use of nanostructured silicon in chronic wound diagnostics and theranostics will be discussed. Finally, the talk will provide an example of the use of porous carrier material for ocular cell therapy.
