Design Concept

Oxford Nanoimaging has redesigned super-resolution instrumentation. We have removed the superfluous elements of traditional fluorescent microscopes and by doing so have created an instrument which is optimally designed to generate high quality single-molecule data. This bottom up design removes instrument complexity and delivers a cost-effective solution, eliminating all requirements for optical tables and dedicated laser laboratories. The instrument operates on a standard laboratory bench, delivering super-resolution capabilities to a broader range of scientific researchers. The instrument supports various modes of operation: single-molecule localization-based super-resolution for quantitative cellular imaging, TIRF and epifluorescence for diffraction-limited fluorescence imaging, single-molecule FRET for measuring molecular interactions in the 2-10 nm range and single particle tracking PALM in cells.

Nanoimager super-resolution

Super-resolution techniques break the 200 nm limit on image resolution imposed by the diffraction of light. The Nanoimager achieves super-resolution by single-molecule localization (dSTORM and PALM). These techniques involve localizing only subsets of fluorophores in consecutive frames with high precision (typically better than 20 nm laterally and 50 nm axially), and reconstructing an image from the positions of the localizations.

The Nanoimager offers four laser lines with powers up to 1 W and the highest available power densities of any commercial instrument, calibrated at the sample plane and reported in real time. The two emission channels enable simultaneous dual-color imaging (four color imaging is possible through interlaced lasers). It supports colocalization studies and the capture of dynamic information for different molecular species.

3D information can be captured using the method of astigmatism for super-resolution detail, and by imaging sequential sections for greater depth.

Unrivaled stability

The Nanoimager microscope unit has a footprint of just 21 cm by 21 cm. The compact design is space-saving, but also reduces aberrations and loss of light in the optical path.

The Nanoimager geometry inherently compensates for drift. It houses specialist materials within the solid microscope body which significantly reduce thermal drift. Multiple software components further eliminate the effect of thermal drift. In addition to the anti-drift features, it has full vibration dampening which is supported by its compact design.

Together, this produces the most stable instrument on the market with no need for an optical table.

Special features

The Nanoimager boasts the largest commercially available field of view, which is evenly illuminated throughout. The large field of view facilitates high-throughput imaging of single molecules and rapid accumulation of sample statistics.

As a Class 1 laser product, the Nanoimager can be safely operated in any room or laboratory.

The advanced sample stage has exceptional positional accuracy and reproducibility.

Autofocusing allows automated data acquisition over multiple fields of view and the rapid overview feature negates the need for oculars.

Whole-body heating to 37°C supports live-cell imaging and avoids the disruptive effect of temperature gradients.

Intelligent data analysis using our custom software suite is provided for all the Nanoimager modes of operation, including super-resolution imaging, smFRET and sptPALM.
