Mitochondrial dynamics refers to the processes of fusion, fission, and transport that aid mitochondria in accomplishing their many roles; including ATP production, oxygen sensing, and homeostasis. Due to their involvement in numerous essential cellular act ...

Background: Fluorescence loss in photobleaching (FLIP) is a widely used imaging technique, which provides information about protein dynamics in various cellular regions. In FLIP, a small cellular region is repeatedly illuminated by an intense laser pulse, ...

Over the last decade, several protein tags have been developed for the specific and covalent labeling of fusion proteins with small organic probes. Among them, SNAP-tag has been used in many applications such as live cell imaging, protein microarrays and t ...
Fluorescence cystoscopy enhances detection of early bladder cancer. Water used to inflate the bladder during the procedure rapidly contains urine, which may contain fluorochromes. This frequently degrades fluorescence images. Samples of bladder washout flu ...
This paper presents our work on a 65k pixel single-photon avalanche diode (SPAD) based imaging sensor realized in a 0.35 mu m standard CMOS process. At a resolution of 512 by 128 pixels the sensor is read out in 6.4ps to deliver over 150k monochrome frames ...
Single-molecule Forster resonance energy transfer (FRET) and photoinduced electron transfer (PET) have developed into versatile and complementary methods for probing distances and dynamics in biomolecules. Here we show that the two methods can be combined ...
For decades chemists have focused on increasing the brightness of fluorophores. In super-resolution microscopy, however, fluorophores that preferentially exist in a non-fluorescent state, but occasionally re-arrange into a fluorescent form, can give better ...
An optical method is presented that allows the measurement of the triplet lifetime of a fluorescent molecule. This is a characteristic specific to each fluorophore. Based on differences in triplet lifetimes of two fluorescent species (autofluorescence vers ...
Fluorescence resonance energy transfer (FRET) efficiency measurements based on acceptor photobleaching of yellow fluorescent protein (YFP) are affected by the fact that bleaching of YFP produces a fluorescent species that is detectable in cyan fluorescent ...
Breast cancer is the most common life-threatening malignancy in women of most developed countries today, with approximately 200,000 new cases diagnosed every year. About 30% of these cases progress to metastatic disease and death. Considering that one-thir ...
