Nanolive’s patented technology
The technology behind Nanolive’s microscopes is unique worldwide and is based on a fundamental patent (US 8,937,722 & EU WO 2011/121523).
The combination of holography and rotational scanning makes Nanolive imaging a revolutionary technology.
Holography offers a unique means to measure cells in their native environment: label-free, non-invasive, manipulation-free, and interference-free. Rotational scanning allows 3D reconstructions, noise robustness, and a resolution far beyond the accepted limit for light.
To achieve optimal results for every measurement, the optics of our technology are completely self-adjusting. It guarantees the best alignment conditions – whatever the environment is.
How does the 3D Cell Explorer produce cell images with better than 200 nm lateral resolution?
Non-invasive optical nanoscopy can achieve such a lateral resolution by using a quasi-2π-holographic detection scheme and complex deconvolution. The spatial frequencies of the imaged cell do not make any sense to the human eye. But these SCATTERED frequencies are converted into a hologram and synthesize a bandpass which has a resolution DOUBLE the one normally available.
What does fixation do to your cells’ morphology?
Since fixation aims to provide a snapshot of a living situation, we visualized the process of fixing living samples with PFA using Nanolive’s 3D Cell Explorer. We conclude that cell structures are affected by the fixation process.
Very few studies have been highlighting or discussing the artifacts arising from phototoxicity during live cell imaging. With Nanolive imaging, a low-power laser beam gets phase-shifted when sent through samples, this phase shift is then used to generate 3D-images of refractive indices of the observed samples. This way this technology gets rid of invasive fluorescent markers, while using low energy exposure regimes is a clear added value that makes it well suited to observe living samples, when compared to epifluorescence imaging. Moreno’s et al results raised the question of how much of our knowledge, particularly about mitochondria, may have been biased by artifacts induced by fluorescence imaging.
