ONI – Nanoimager
Oni Nanoimager is a benchtop super-resolution microscope for imaging applications, featuring dSTORM, PALM, PAINT, SPT, and smFRET imaging technologies.
dSTORM
Direct Stochastic Optical Reconstruction Microscopy (dSTORM) relies on the stochastic activation of single fluorophores that blink from “off” to “on”, and quickly back to “off”. The process is repeated many times, activating just one molecule within a diffraction-limited region at a time.
Best for: very high resolution, molecular distributions in fixed cells
PALM
Photoactivated Localization Microscopy (PALM) uses photoactivatable fluorophores to resolve spatial details of tightly packed molecules. Once activated, fluorophores emit for a short period but eventually bleach. The laser stochastically activates fluorophores until all have emitted.
Best for: protein dynamics, organization and quantification, in fixed and live samples
PAINT
In Point Accumulation for Imaging in Nanoscale Topography (PAINT), single-molecule localizations are achieved using transient binding of fluorophores to targeted proteins. PAINT is commonly performed with DNA strands < 10 nt. Like other SMLM techniques, it can reach spatial resolutions of 20 nm.
Best for: biomolecular organization and quantification, in fixed samples
Single-particle tracking
Single-Particle Tracking (SPT) allows the motion of individual particles to be followed in vitro or in living cells, to obtain information on their dynamic behavior over time.Trajectories can be extracted with a resolution of up to milliseconds.
Best for: protein dynamics and tracking, in live samples or in solution
Single – molecule FRET (smFRET)
During single-molecule Förster Resonance Energy Transfer (smFRET), the emission energy of a donor fluorophore is transferred to an acceptor, which subsequently fluoresces when in close proximity. It enables distances between single molecules to be measured at a scale of 1-10 nanometers.
Best for very high resolution, molecular distributions in fixed cells
