ABSTRACT

Nanoprobes are nanoscale systems that can be designed smartly to perform several functions when they are on a journey or mission in a human body or in an underground oil reservoir. In either case, we would like to design them so they may be motion controlled, selectively attach to a specific target, deliver a load, and report on the local environment, including the molecular composition, temperature, Ph, pressure, salinity, etc. One important element of the probe is the active element, which is usually a nanoparticle of some material or combination of material.

In this talk I will present on silicon nanoparticle-based composites as an effective element for performing multi-tasking. I will focus on the formation of hybrid iron oxide-nanoparticles with luminescent silicon nanoparticle core, providing optical, luminescence, and magnetic functionality. In the process, the H-Si terminated silicon nanoparticle act as a reducing and growth element of the iron ions.
