Microfluidic devices called lab-on-a-chips utilize two kinds of characterization of a biosample, which are based on spectrofluorimetric and spectrophotometric methodologies. Lab-on-a-chips are equipped with an optical instrumentation and a software system that allow detecting of the optical signals and their processing into spectral characteristics. In the paper, technology of lab-on-a-chip (cytometer...
W pracy przedstawiono krzemowo-szklany chip mikrofluidyczny tzw. mikrocytometr. Jest to miniaturowe urządzenie do analizy parametrów różnych komórek (przepływającego obiektu biologicznego) wprowadzonych do układu mikrokanałów. Prezentowany mikrocytometr przystosowany jest do wprowadzania światła prostopadle do kierunku przepływu badanej próbki. Do oświetlania próbki opracowano miniaturowe krzemowo-szklane...
In this work for the first time, we report micro-cytometer equipped with miniature vacuum field emission light source (FELS) for fluorimetric measurements and able to carry on transmission/absorption measurements in VIS/NIR spectra. FELS sources utilizes cold electron field emission phenomena from carbon nanotubes. They are working on wavelengths adjusted to fluorescent markers used in biochemical...
