Journal ArticleDOI
Quantitative determination of size and shape of surface-bound DNA using an acoustic wave sensor.
Achilleas Tsortos,George Papadakis,George Papadakis,Konstantinos Mitsakakis,Konstantinos Mitsakakis,Kathryn A. Melzak,Kathryn A. Melzak,Electra Gizeli,Electra Gizeli +8 more
TL;DR: The application of an acoustic wave device for characterizing the conformation of DNA molecules tethered to the device surface via a biotin-neutravidin interaction provides quantitative information on the size and shape of the tethered molecules.
Journal ArticleDOI
All-plastic, low-power, disposable, continuous-flow PCR chip with integrated microheaters for rapid DNA amplification
Despina Moschou,Nikolaos Vourdas,George Kokkoris,George Papadakis,John Parthenios,Stavros Chatzandroulis,Angeliki Tserepi +6 more
TL;DR: In this article, a low-cost and low-power, continuous-flow microfluidic device for DNA amplification by polymerase chain reaction (PCR) with integrated heating elements, on a commercially available thin polymeric substrate (Pyralux® Polyimide), is presented.
Journal ArticleDOI
Shear acoustic wave biosensor for detecting DNA intrinsic viscosity and conformation: A study with QCM-D
TL;DR: It is shown that acoustic measurements can clearly distinguish between ds-DNA of same shape but various sizes and same mass and size but various shapes, and a mathematical formula is presented relating the length of straight, surface-protruding DNA to the acoustic ratio DeltaD/Deltaf.
Journal ArticleDOI
Plasma nanotextured polymeric lab-on-a-chip for highly efficient bacteria capture and lysis
Katerina Tsougeni,George Papadakis,M. Gianneli,Aristea Grammoustianou,Vassilios Constantoudis,Bruno Dupuy,Panagiota S. Petrou,Sotirios E. Kakabakos,Angeliki Tserepi,Electra Gizeli,Evangelos Gogolides +10 more
TL;DR: A sample preparation module comprising bacteria cell capture and thermal lysis on-chip with potential applications in food sample pathogen analysis and excellent selectivity was obtained in a sample containing S. Typhimurium and E. coli bacteria.
Journal ArticleDOI
Direct detection of DNA conformation in hybridization processes.
George Papadakis,Achilleas Tsortos,Florian Bender,Florian Bender,Elena E. Ferapontova,Electra Gizeli,Electra Gizeli +6 more
TL;DR: This work proposes a mass-independent sensing principle based on the quantitative monitoring of the conformation of the immobilized single-strand probe and of the final hybridized product that is applied to single-nucleotide polymorphism detection and suggests that DNA conformation probing with acoustic wave sensors is a much more improved detection method.
