Characterization of FRET sensor
Datinská, Vladimíra ; Klepárník, Karel ; Belšánová, B. ; Minárik, M. ; Foret, František
In this study, we present characterization of sensor based on Fӧrster resonance energy\ntransfer (FRET). The sensor is composed of ssDNA chain attached to a laboratory\nsynthesized quantum dot (QD). A complementary chain of a sample is labeled by a\nluminescent dye. When the dsDNA hybrid is formed, the energy from the QD (donor)\nis transferred to the dye (acceptor) and FRET is observed as a decrease of QD\nluminescence emission intensity and an increase of dye luminescence emission\nintensity.

New sensor for DNA mutation detection
Datinská, Vladimíra ; Klepárník, Karel ; Minárik, M. ; Foret, František
We present a design and synthesis of a new sensor intended for the genomic analysis in molecular cancer research. This sensor is based on the Förster resonance energy transfer (FRET) and can be used for the detection of complementary oligonucletide chains based on probe hybridization. Quantum dots (QDs) with their unique optical properties serve as suitable donors of energy in FRET.
