Abstract
Super-resolution imaging of single DNA molecules via point accumulation for imaging in nanoscale topography (PAINT) has great potential to visualize fine DNA structures with nanometer resolution. In a typical PAINT video acquisition, dye molecules (YOYO-1) in solution sparsely bind to the target surfaces (DNA) whose locations can be mathematically determined by fitting their fluorescent point spread function. Many YOYO-1 molecules intercalate into DNA and remain there during imaging, and most of them have to be temporarily or permanently fluorescently bleached, often stochastically, to allow for the visualization of a few fluorescent events per DNA per frame of the video. Thus, controlling the fluorescence on-off rate is important in PAINT. In this paper, we study the photobleaching of YOYO-1 and its correlation with the quality of the PAINT images. At a low excitation laser power density, the photobleaching of YOYO-1 is too slow and a minimum required power density was identified, which can be theoretically predicted with the proposed method in this report.

Abstract
In standard steady-state fluorescence anisotropy (FA) DNA-based assays, the ligand binding to a given receptor is typically signalled by the rotational correlation time changes of the tracer. Herein, we report a radically different strategy that relies on the peculiar excited state lifetime features of the SYBR Green (SG) dye. This DNA-binding probe exhibits a drastically short lifetime in solution, leading to a high FA signal. Its complexation to oligonucleotides determines a singular and very large depolarization depending on the concerted effects of extreme lifetime enhancement and resonance energy homotransfer. On the basis of ligand-induced changes in the molar fractions of bound and free forms of SG, the approach provides an unprecedented means for the FA monitoring of the ligand binding to short DNA molecules, allowing the elaboration of a variety of intercalator displacement assays and label-free biosensors that involve diverse DNA structures (duplex, hairpin, G-quadruplex and single-stranded), ligand types (ion, small organic molecule and protein) and binding modes (intercalation, minor groove, allosteric switch). These findings open up promising avenues in the design of a new generation of FA assays.

Abstract
A unique interaction between the cyanine dye and negatively charged quantum dot is used to construct a signal-on biaptameric quantum dot (QD) Förster resonance energy transfer (FRET) beacon for protein detection and distinct aptamer characterization. The beacon comprises a pair of aptamers, one intercalated with the cyanine dye (YOYO-3) and the other conjugated to a negatively charged, carboxyl-QD. When the target protein is present, structural folding and sandwich association of the two aptamers take place. As a consequence, YOYO-3 is displaced from the folded aptamer and transferred to the unblocked QD surface to yield a target concentration-dependent FRET signal. As a proof-of-principle, we demonstrate the detection of thrombin ranging from nanomolar to submicromolar concentrations and confirm the dye translocation using cylindrical illumination confocal spectroscopy (CICS). The proposed beacon provides a simple, rapid, signal-on FRET detection for protein as well as a potential platform for distinct aptamer screening.
