Surface enhanced Raman spectroscopy
Maděránková, D. ; Provazník, I. ; Klepárník, Karel
The signal of Raman scattering in carotene solutions, enhanced on silver colloid particles was studied. The dependence of the enhancement factor on the concentration of silver particles demonstrates the potential of the method for biological applications.
Potenciál kvantových teček při detekci jediné molekuly v buňkách a organelách
Přikryl, Jan ; Klepárník, Karel ; Svobodová, Ivona ; Hezinová, Věra ; Lišková, Marcela ; Preisler, J. ; Foret, František
This contribution is devoted to quantum dots usage for cell imaging in fluorescence microscopy. Fluorescence excitation by evanescence wave (caused by total internal reflection) is compared with conventional epifluorescence microscopy.
Studium transportu iontů přes modelové fosfolipidové membrány
Navrátil, Tomáš ; Šestáková, Ivana ; Mareček, Vladimír
Synthetically prepared model phospholipid bilayers (PLBs) in the form of black membranes, vesicles or supported membranes, with incorporated ionophores or real ion channels (i.e., artificially synthesized or gained from real living cells, e.g. protoplasts) are promising for study and simulations of transporting processes across the real cell membranes and the membranes surrounding sub-cellular structures. The electrochemical methods were found to be very suitable and sensitive enough for characterization of such processes.
