Nanoshells are a novel class of optically tunable nanoparticles that consist dielectric core surrounded by thin gold shell. Based on the relative dimensions shell thickness and radius, nanoshells may be designed to scatter and/or absorb light over broad spectral range including near-infrared (NIR), wavelength region provides maximal penetration through tissue. The ability control both wavelength-dependent scattering absorption offers opportunity design which provide, in single nanoparticle,...
Metal nanoshells are a novel type of composite spherical nanoparticle consisting dielectric core covered by thin metallic shell which is typically gold. Nanoshells possess highly favorable optical and chemical properties for biomedical imaging therapeutic applications. By varying the relative dimensions shell, resonance these nanoparticles can be precisely systematically varied over broad region ranging from near-UV to mid-infrared. This range includes near-infrared (NIR) wavelength where...
Advances in scattering-based optical imaging technologies offer a new approach to noninvasive point-of-care detection, diagnosis, and monitoring of cancer. Emerging photonics provide cost-effective means image tissue vivo with high resolution real time. Advancing the clinical potential these strategies requires development contrast agents targeted specific molecular signatures disease. We describe use novel class based on nanoshell bioconjugates for living cells. Nanoshells significant...

Currently, separate diagnostic and therapeutic modalities are required for the diagnosis treatment of cancer. In many cases, present standard care requires invasive surgical procedures and/or other treatments associated with significant side effect profiles, high cost, poor clinical outcome. A single technology dual diagnostic/therapeutic capabilities would potentially yield savings in time cost diagnosing treating cancers. this paper, we discuss gold nanoshell bioconjugates their role...
Purpose: Encapsulation of contrast agent within a nanoporous matrix has been shown to enhance performance. Previous investigators have an up 40-fold increase in T1 image enhancement gadolinium with encapsulation carbon nanotubes. In this study we examined silicon as means superparamagnetic iron oxide nanoparticles (SPIONs) using particle-agarose phantom. Methods: 1μm discoidal pSi particles were loaded 30 nm SPIONs through capillary action. Loaded particle preparations along free SPION...
We have shown that process effects induced by extending the post-exposure bake temperature in flow of chemically amplified photoresists can lead to significant improvements depth-of-focus (DOF) and exposure latitude (EL) small geometry printing capability. Due improved acid dose contrasts a balanced optimization diffusion presence quencher, PEB increase has enabled iso semi-dense space 0.2 ?m below with large DOF, using binary masks 248 nm lithography without expensing iso-dense bias. The...
We have shown that process effects induced by extending the softbake (SB) and post-exposure bake (PEB) temperature in flow of chemically amplified photoresists can lead to significant improvements depth-of-focus (DOF) exposure latitude (EL) small geometry printing capability (resolution). Through careful optimization SB PEB temperature, dense line space structures 160 nm below be printed with substantially big margin, using binary masks 248 lithography under half annular illumination mode....
In this paper, we presented a new furnace loading procedure with specially-prepared monitor wafer (SPMW) to prevent scrapping wafers placed at top slot of the boat and other slots if lot has < 25 wafers. These showed V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">gs</sub> OOS on high side. Our investigation that nonuniform behavior is due inconsistent phosphorus atoms diffused across boat. The outgassing occurs during p-body anneal from...
