230 fold fluorescence enhancement by 3D Rhodamine B coated polystyrene photonic crystals

Eftekhari E., Li Q., Li X., Cole I.S., Li Q., Li X., Griffith University, AU

We report a 230-fold fluorescence enhancement with fluorescent polystyrene based three-dimensional (3D) colloidal photonic crystals (F-CPhCs) that can be readily fabricated over large areas. A simple and reproducible method was developed to synthesise novel fluorescent [...]

Platinum Bowtie Nanostructure Arrays for Massively Parallel Single Molecule Detection Based on Fluorescence Enhancement Phenomena

Saito T., Takahashi S., Obara T., Itabashi N., Imai K., Hitachi High-Technologies Corporation, JP

To enable not only long sequence read but also high throughput in a DNA sequencer, the single molecule sequencing method based on direct observation of processive DNA polymerization is very promising. In this method, only [...]

DNA Detection Using Metal-Fluorescence Interactions on Two-Dimensionally Assembled Gold Nanoparticles

Nakahara M., Taniguchi S., Inoue T., Hitachi Ltd., JP

We developed a novel DNA detection system using a single stranded probe oligonucleotide with a fluorophore immobilized on two-dimensionally assembled gold nanoparticles. This system enables the detection of amplified DNAs without fluorescence labeling. In the [...]
