LNA functionalized gold nanoparticles as probes for double stranded DNA through triplex formation.
Nanoparticle modified LNA probes have been used for colorimetric identification of double stranded DNA via parallel triplex formation, eliminating the need for prior denaturation of the target duplex.
متن کاملFunctionalized nanoparticles for bioanalysis by SERRS.
Metallic nanoparticles can be used as basic materials for a wide variety of purposes including building blocks for nanoassemblies, substrates for enhanced spectroscopies such as fluorescence and Raman and as labels for biomolecules. In the present paper, we report how silver and gold nanoparticles can be functionalized with specific biomolecular probes to interact in a specific manner with a ta...
متن کاملNanosensing protein allostery using a bivalent mouse double minute two (MDM2) assay.
The tumor suppressor protein, p53, is either mutated or absent in >50% of cancers and is negatively regulated by the mouse double minute (MDM2) protein. Understanding and inhibition of the MDM2-p53 interaction are, therefore, critical for developing novel chemotherapeutics, which are currently limited because of a lack of appropriate study tools. We present a nanosensing approach to investigate...
متن کاملHighly sensitive detection of dye-labelled DNA using nanostructured gold surfaces.
Careful control of surface chemistry results in strong surface enhanced resonance Raman scattering from dye-labelled oligonucleotides assembled on nanostructured gold surfaces, releasing their potential as reliable enhancing surfaces.
متن کاملPositively charged silver nanoparticles and their effect on surface-enhanced Raman scattering of dye-labelled oligonucleotides.
Improved positively charged nanoparticles are described to provide a simplified SERS substrate for DNA detection. Complete flocculation of the nanoparticles is prevented due to the controlled analyte induced aggregation. This provides a stable aggregation state which significantly extends the analysis window simplifying DNA detection by SERS.
