<h3>Összefoglaló:</h3>
<p><span style="font-size: medium;">The advent of single molecule imaging and manipulation techniques has brought about a radically new perspective on probing natural phenomena. Rather than observing quantities of the </span><span style="font-size: medium;">bulk – averages over various ensembles – these techniques permit monitoring at the individual particle level. In this talk I will present our theoretical investigation on nanoscale fluorescence blinking, single photon counting statistics and rotary biomolecular motors driven by single particle data. In particular, I will describe the multiple recombination center model first proposed to explain quantum dot blinking, a fluctuation of the fluorescence emission intensity with complicated power-law statistics. Our power-spectral statistical analysis revealed the underlying universality of blinking found in systems such as nanorods, nanowires and even organic dyes. More recently, the modeling has been extended to spatio-temporal blinking in reduced graphene oxide. I will also discuss an important aspect of single particle spectroscopy, the appropriate treatment of photon counting statistics. Finally, I will present a theory of elastically coupled chemical reactions developed to explain recent single molecule imaging and manipulation experiments on ATPase.</span></p>
