How does the synthetic pathway described in the publication differ from standard methods? Research by Naomi Halas and co-workers from Rice University has shown that the same core-shells can be used in very different applications, such as SERS, cancer treatment or steam generation. Surfaced Enhanced Raman Spectroscopy (SERS)), cancer treatment, controlled drug release, medical imaging or photocatalysis. Depending on the metals used as a shell material and the shell morphology, core-shell particles can be used in surface enhanced spectroscopies (i.e. The versatility of the core-shell platform can be visualized by the example of silica-metal core-shell nanostructures, which we described in Adv. The number of possible combinations is huge. core shape and size, shell thickness), core and shell materials, morphology of the shell, incorporating of additional molecules or particles into shell, etc. One of the reasons is that their properties can be tailored to specific applications by selection of geometry (i.e. The core-shell particles in general have a great potential for use in many applications. What are the applications of metallic-core nano spheres? Their work was recently published in the Journal of Nanotechnology: Beilstein J. The synthesis problems have now been largely resolved which opens up a route to cost-effective production and further application development. The potential utility of these nano-structures is obvious but the challenges in scalable synthesis and control of the properties have held back wider adoption. These new particles have applications in nanomedicine as well as in opto-electronics. The potential applications of a new type of core-shell nanoparticle, with tunable titania shells, are covered in this interesting interview with Bartłomiej Jankiewicz of the Institute of OptoElectronics at the Military University of Technology in Warsaw.
