Responses

electron microscope
electron microscope

fluorescence microscope
fluorescence microscope

light-based microscope
light-based microscope

scanning tunneling microscope

Answer 1

The most recently developed type of microscope among the options provided is the **scanning tunneling microscope** (STM). The STM was invented in 1981 by Gerd Binnig and Heinrich Rohrer, allowing for imaging surfaces at the atomic level and enabling new advances in nanotechnology and surface science. While fluorescence and electron microscopes have been refined and developed over the years, the STM represents a more recent innovation in the field of microscopy.
