Question
Which type of microscope was developed most recently
Answers
GPT-5 mini
It depends how you define "type," but among the major classes of microscopes the most recently developed are in the nano‑scale/probe and super‑resolution families.
Quick timeline (major milestones):
- Optical (compound) microscope: late 1500s–1600s.
- Transmission electron microscope (TEM): Ernst Ruska, 1931.
- Scanning electron microscope (SEM): early concepts 1930s, practical instruments mid‑1960s.
- Scanning tunneling microscope (STM): G. Binnig & H. Rohrer, 1981.
- Atomic force microscope (AFM): Binnig, Quate & Gerber, 1986.
- Super‑resolution fluorescence methods (e.g., STED, PALM, STORM): STED (Stefan Hell) 1994; PALM/STORM ~2006.
- Modern cryo‑EM “resolution revolution”: major advances around 2010s.
So: if you mean single most recent among standard categories, AFM (1986) came after STM (1981). If you include optical super‑resolution techniques, those (1994–2006) are even more recent — and the biggest practical advances in cryo‑EM are from the 2010s.
If you had a specific set of choices, tell me them and I’ll pick the correct one.
