In the current study, the team has now developed a new technique known as "Ultrafast Dark-field Momentum Microscopy ...

However, traditional dark-field microscopy is limited by the diffraction barrier and often requires complex, bulky setups with precise alignment. Super-resolution imaging techniques, which can ...

Near-field imaging techniques place very few requirements ... However, they require fluorophores that can be cycled between bright and dark states many times without photobleaching.
