Monitoring Simultaneous Distance and Orientation Changes in Discrete Dimers of DNA Linked Gold Nanoparticles.
Important optical properties of discrete pairs of DNA tethered gold nanoparticles, including their scattering cross-section and resonance wavelength, depend both on the dimer structure and the refractive index of their immediate environment. We show that far-field polarization microscopy aids the optical identification and interpretation of structural changes including hinge motions and nanosca...
متن کاملControl of protein orientation on gold nanoparticles.
Gold nanoparticles (Au NPs) have attracted much attention due to their potential applications in nano-medicine. While numerous studies have quantified biomolecular adsorption to Au NPs in terms of equilibrium binding constants, far less is known about biomolecular orientation on nanoparticle surfaces. In this study, the binding of the protein α-synuclein to citrate and (16-mercaptohexadecyl) tr...

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Photonic interaction between quantum dots and gold nanoparticles in discrete nanostructures through DNA directed self-assembly.
Discrete nanostructures of CdSe@ZnS QDs and Au NPs were prepared and the photonic interactions between the QDs and Au NPs were systematically investigated. We found that the Au/QD ratio, separation distances between Au NPs and QDs, and the size of the Au NPs in a given discrete nanostructure all affect the interaction between Au NPs and QDs.
متن کاملDisorder in DNA-linked gold nanoparticle assemblies.
We report experimental observations on the effect of disorder on the phase behavior of DNA-linked nanoparticle assemblies. Variation in DNA linker lengths results in different melting temperatures of the DNA-linked nanoparticle assemblies. We observed an unusual trend of a nonmonotonic "zigzag" pattern in the melting temperature as a function of DNA linker length. Linker DNA resulting in unequa...
