چکیده
We demonstrate here a DNA-based conformationally switchable nanodumbell structure that modulates the interparticle distance between two gold-silver core-shell nanoparticles to induce significant changes in the SERS signal.

Graphene oxide based surface-enhanced Raman scattering probes for cancer cell imaging.
The intrinsic Raman signals provide the potential of graphene oxide (GO) for cellular imaging. Herein, novel surface-enhanced Raman scattering (SERS) labels based on GO-Ag nanoparticle (NP) composites are developed for fast cellular probing and imaging. The optimum SERS signals of the hybrids can be well controlled by adjusting the weight ratio between AgNO(3) and GO. Utilizing GO-AgNPs as the ...
متن کاملPeptide-guided surface-enhanced Raman scattering probes for localized cell composition analysis.
The ability to control the localization of surface-enhanced Raman scattering (SERS) nanoparticle probes in bacterial cells is critical to the development of analytical techniques that can nondestructively determine cell composition and phenotype. Here, selective localization of SERS probes was achieved at the outer bacterial membrane by using silver nanoparticles functionalized with synthetic h...
متن کاملSurface-enhanced Raman spectra of medicines with large-scale self-assembled silver nanoparticle films based on the modified coffee ring effect
We report here a simple and innovative method to prepare large-scale silver nanoparticle films based on the controlled coffee ring effect. It is demonstrated that the films can be used as surface-enhanced Raman scattering probes to detect low-concentration medicines. Silver nanoparticles with the average size about 70 nm were prepared by reduction of silver nitride. In our experiment, the coffe...

متن کاملHighly reproducible and sensitive surface-enhanced Raman scattering from colloidal plasmonic nanoparticle via stabilization of hot spots in graphene oxide liquid crystal.
Although it is now well recognized that plasmonic gold/silver nanoparticle based aggregates having electromagnetic hot spots are responsible for high sensitivity in surface-enhanced Raman spectroscopy (SERS), the high yield and reproducible production of such nanostructures are challenging and limit their practical application. Here we show a graphene oxide (GO) based approach in generating sta...
