Key Features and Technologies
The 3i/Atlas platform incorporates a range of advanced technologies that contribute to its exceptional performance. These include:
- Adaptive Optics (AO): Corrects for aberrations in the optical path, resulting in sharper, more detailed images. AO is especially crucial when imaging deep within tissues or complex materials.
- Lattice Light Sheet Microscopy (LLSM): Minimizes phototoxicity and photobleaching, allowing for long-term, live-cell imaging with minimal disruption to the sample.
- Spinning Disk Confocal Microscopy: Provides rapid, high-resolution optical sectioning for three-dimensional imaging.
- Multi-Photon Microscopy: Enables deep tissue imaging with reduced scattering and background noise.
- Software Control and Analysis: The platform is controlled by sophisticated software that allows for precise control of imaging parameters, automated data acquisition, and advanced image analysis.
Adaptive Optics: Sharpening the Image
Adaptive optics is a critical component of the 3i/Atlas platform. It works by measuring and correcting for wavefront distortions caused by refractive index variations within the sample and the optical system itself. These distortions can blur the image and reduce resolution, particularly when imaging deep within tissues or complex materials.
The AO system in the 3i/Atlas platform typically consists of a wavefront sensor and a deformable mirror. The wavefront sensor measures the distortions in the light path, and the deformable mirror adjusts its shape to compensate for these distortions. This process is performed in real-time, ensuring that the image is always as sharp as possible.
Practical Example: Consider imaging a thick tissue sample. As light passes through the tissue, it encounters variations in refractive index, causing the light rays to bend and distort. Without adaptive optics, the resulting image would be blurry and lack detail. However, with AO, the system can correct for these distortions, producing a clear, high-resolution image of the tissue.
Lattice Light Sheet Microscopy: Gentle Imaging for Live Cells
Lattice light sheet microscopy is a revolutionary technique that minimizes phototoxicity and photobleaching, making it ideal for long-term, live-cell imaging. Traditional microscopy techniques often expose the sample to high levels of light, which can damage cells and alter their behavior. LLSM addresses this issue by using a thin sheet of light to illuminate only the plane of interest, reducing the overall light exposure and minimizing phototoxicity.
In LLSM, a lattice light sheet is generated by rapidly scanning a focused beam of light across the sample. The emitted light is then collected by a separate objective lens, which is positioned perpendicular to the light sheet. This orthogonal illumination and detection scheme minimizes the amount of light that the sample is exposed to, allowing for long-term imaging with minimal disruption to cellular processes.
Real-World Application: Researchers use LLSM to study cell division, migration, and differentiation in real-time. By minimizing phototoxicity, they can observe these processes without altering the cells' natural behavior.
Spinning Disk Confocal Microscopy: Rapid 3D Imaging
Spinning disk confocal microscopy is a powerful technique for rapid, high-resolution optical sectioning. It uses a spinning disk with multiple pinholes to scan the sample, eliminating out-of-focus light and producing clear, three-dimensional images. This technique is particularly useful for imaging thick samples and for capturing dynamic events in living cells.
The spinning disk contains thousands of pinholes arranged in a specific pattern. As the disk spins, the pinholes scan the sample, allowing only light from the focal plane to pass through to the detector. This eliminates out-of-focus light, resulting in sharper, more detailed images. The rapid scanning speed of the spinning disk allows for fast image acquisition, making it possible to capture dynamic events in real-time.
Case Insight: Scientists use spinning disk confocal microscopy to study the interactions between different cells in a tissue sample. By acquiring a series of optical sections, they can reconstruct a three-dimensional image of the tissue and analyze the spatial relationships between the cells.
Multi-Photon Microscopy: Deep Tissue Imaging
Multi-photon microscopy is a non-linear optical technique that allows for deep tissue imaging with reduced scattering and background noise. It uses pulsed lasers to excite fluorophores in the sample, and the emitted light is detected to create an image. Because the excitation occurs only at the focal point of the laser, multi-photon microscopy provides excellent optical sectioning and minimizes photobleaching.
In multi-photon microscopy, two or more photons are simultaneously absorbed by the fluorophore, leading to excitation. The probability of this simultaneous absorption is very low, so it only occurs at the focal point of the laser where the photon density is high. This results in excellent optical sectioning, as only the fluorophores in the focal plane are excited.
Experience: Researchers use multi-photon microscopy to image blood vessels, neurons, and other structures deep within tissues. The reduced scattering and background noise allow them to obtain clear, high-resolution images even at depths of several millimeters.
