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.

Multi-step synthesis of caspase-3 sensor based on Förster resonance energy transfer
 Lišková, Marcela ; Klepárník, Karel ; Pazdera, P. ; Foret, František
Programmed cell death or apoptosis is regulated process of cell suicide. The central role in apoptosis play cysteine proteases called caspases. Caspases recognize tetra-peptide sequences Asp-Glu-Val-Asp (DEVD) on their substrates and hydrolyze peptide bonds after aspartic acid residues. Various techniques for the determination of caspase-3 are commercially available e.g. Enzyme Linked Immuno-Sorbent Assay (ELISA), Western blotting or flow cytometric analysis. The products of the cleavage can be detected by spectrophotometry, fluorimetry, chemiluminescence (CL) or ELISA. In this work, we suggested fluorescent sensor based on Förster Resonance Energy Transfer (FRET) to determine caspase-3 in cell nucleus or cytoplasm by apoptosis for very fast analysis by fluorescence microscopy without sample destroying.
