This project grew out of my independent fellowship at Princeton Physics and @cpbf.bsky.social, supported by @princeton.edu's Dean for Research Innovation Fund. Grateful to many who made this possible, especially Yaakov Clenman, Alejandra Duran, @toettch.bsky.social, and @harrymcnamara.bsky.social

The gains in resolution, contrast, and optical sectioning enable imaging in low-SNR conditions and single-molecule tracking in living fruit fly embryos, revealing how individual transcripts diffuse in their intracellular environment

In complex multicellular systems, like organoids and gastruloids, resolution is often limited by scattering-induced out-of-focus background, not diffraction.

2P-OPM suppresses this background, maintains subcellular resolution at depth, and works with standard sample mounting
