Eric Betzig

Photoactivated localization microscopy instrument

United StatesEvidence: high confidenceChecked July 2026

Eric Betzig co-invented photoactivated localization microscopy, a super-resolution optical instrument that can distinguish biological structure below the usual diffraction limit. PALM's molecular-level images made it a durable tool for researchers studying cells, disease mechanisms and the organization of living systems.
