- What is expansion microscopy and how does it work?
- Expansion microscopy is a revolutionary technique that increases the size of a sample, allowing for the visualization of details smaller than the resolution limit of traditional optical microscopes.
- What are some applications of expansion microscopy?
- The applications of expansion microscopy are wide-ranging, including studying cellular structures such as microtubules and synapses, exploring eye pathologies related to photoreceptor cells, and examining plankton structures. Its accessibility fosters broader research potential.
- Describe the steps involved in expansion microscopy.
- The method involves injecting small molecules into cells that bind to proteins and organelles, then embedding them in a gel, which is expanded by injecting water. This expansion allows for the observation of details previously invisible with standard microscopy.
- What recent advancements have been made in expansion microscopy?
- Researchers at MIT have published a refined protocol for expansion microscopy, making it easier and more accessible for scientists worldwide. The improved method uses a new type of absorbent polymer, making the process even more effective.
- What are the limitations or concerns surrounding expansion microscopy?
- While the technique offers significant advantages, some remain skeptical due to concerns about potential distortion during the expansion process. However, researchers argue that the deformation is isotropic and controlled for in the protocols.
