A new fluorescence microscopy method developed by researchers at the University of California, Berkeley, can improve the resolution of images of biological samples down to the Ångström scale. This will allow scientists to study the structure and function of proteins and other biomolecules in much greater detail.

The new method, called MINFLUX (minimum fluorescence excitation), uses a combination of advanced optics and computational imaging to reduce the amount of light needed to excite fluorescent molecules. This allows for imaging of samples with minimal damage or perturbation.

The researchers were able to use MINFLUX to image a variety of biological samples, including proteins, nucleic acids, and bacteria. They were able to resolve features as small as 1 Ångström, which is about the size of a single atom.

MINFLUX is a promising new tool for studying the structure and function of biomolecules. It has the potential to revolutionize our understanding of cellular processes and disease mechanisms.

Here are some of the key features of MINFLUX:

* High resolution: MINFLUX can achieve a resolution of 1 Ångström, which is about the size of a single atom.

* Low photodamage: MINFLUX uses a combination of advanced optics and computational imaging to reduce the amount of light needed to excite fluorescent molecules. This allows for imaging of samples with minimal damage or perturbation.

* Wide range of applications: MINFLUX can be used to image a variety of biological samples, including proteins, nucleic acids, and bacteria.

MINFLUX is a powerful new tool for studying the structure and function of biomolecules. It has the potential to revolutionize our understanding of cellular processes and disease mechanisms.
