Physically or externally stimulated nanostructures often employ multimodality and show encouraging results at preclinical stage in cancer therapy. Specially designed smart such as hybrid are responsive to external physical stimuli light, magnetic field, electric, ultrasound, radio frequency, X-ray, etc. These physically have been widely explored nonconventional innovative “nanotheranostics” therapies. (particularly light) nanotheranostics provide a unique combination of important properties...
This roadmap consolidates recent advances while exploring emerging applications, reflecting the remarkable diversity of hardware platforms, neuromorphic concepts, and implementation philosophies reported in field. It emphasizes critical role cross-disciplinary collaboration this rapidly evolving
We report on circularly polarized Gaussian beam spin angular momenta that can be inverted upon scattering with quadrupole plasmon modes. The conditions for such conversion are met high-angle collection, dark-field microscopy spherical plasmonic particles. further silvered nanoporous silica microparticles exhibit a strong nonlinearity in their scattering, specifically reverse saturated (RSS), when exposed to high laser power densities the sample of ca. 5 GW/cm2. Handedness by these is only...
Progress in nanomedicine has enabled the development of smart hybrid nanostructures (HNSs) for brain cancer theranostics, a novel platform that can diagnose while concurrently beginning primary treatment, initiating secondary treatments where necessary, and monitoring therapy response. These HNSs release guest molecules/cargoes directly to tumors response external physical stimuli. Such stimulation is generally referred as remote stimuli which be externally applied examples include...
Fe3O4–Au core–shell magnetic-plasmonic nanoparticles are expected to combine both magnetic and light responsivity into a single nanosystem, facilitating combined optical magnetic-based nanotheranostic (therapeutic diagnostic) applications, for example, photothermal therapy in conjunction with resonance imaging (MRI) imaging. To date, the effects of plasmonic gold shell on an iron oxide nanoparticle core applications remains largely unexplored. For this study, we quantified efficacy cores...
Abstract Cloud data workloads require both high capacity at low cost and access rates. Hard Disk Drives are the dominant media in this application as they cost, however, Drive technology is seeing declining rates a slowdown scaling. Holographic storage could disrupt cloud since it may offer However, challenge with rewritable holographic durability due to erasure. Here we present workload aware energy optimization framework show that erasure can be managed. We investigated optimal Fe...
Optical properties of metal nanostructures, governed by the so-called localised surface plasmon resonance (LSPR) effects, have invoked intensive investigations in recent times owing to their fundamental nature and potential applications. LSPR scattering from nanostructures is expected show symmetry oscillation mode particle shape. Therefore, information on polarisation crucial for identifying different modes within one distinguish differently shaped particles sample. On contrary, state light...
The indiscriminate and sporadic use of antibiotics has contributed to the emergence drug resistance phenomenon in bacteria including but not limited Staphylococcus aureus. These drug-resistant have been threatening safety hospitals adversely affecting human health. Here we report a strategy design photo-stimulated theranostic nanoprobes against methicillin-resistant aureus (MRSA) "superbug" USA300. nanocapsule probe is based on gold nanorods (GNRs) coated with pegylated thiol, mPEG-SH, which...
Optical studies of magnetite-gold, core-shell nanostructures reveal a spectral drift between the scattering and extinction, accompanied by interesting photothermal effects.
Polyimides (PI) are a class of dielectric polymer used in wide range electronics and electrical engineering applications from low-voltage microelectronics to high voltage isolation. They well appreciated because their excellent thermal, electrical, mechanical properties, each which need be optimized uniquely depending on the end application. For example, for high-voltage applications, final breakdown field properties must optimized, both dependent curing process physico-chemical PI. The...
CuZnSe2 (CZSe) is an important ternary semiconductor comprised of earth-abundant elements with a suitable bandgap for visible light absorption and structural/stoichiometric versatility that make it promising candidate photovoltaic applications.

Remarkably, for silvered...
Magnetic-plasmonic, Fe3O4-Au, core-shell nanoparticles are popular in many applications, most notably therapeutics and diagnostics, thus, the imaging of these nanostructures biological samples is high importance. These typically imaged material by dark field scatter imaging, which requires an even distribution sample and, therefore, nanoparticle doses, potentially leading to toxicology issues. Herein, we explore nonlinear optical properties magnetic coated with various thicknesses gold using...
Holographic Storage is an old idea that has always promised high density and fast random access, but never been commercially competitive with Hard Disk Drives (HDDs) Solid State Devices (SSDs). In Project HSD at Microsoft Research we asked the question: “Does holographic storage finally make sense for cloud storage?” This paper describes our journey towards answering this question. We achieved 1.8x higher than previous state of art, using commodity components available today leveraging...
