Microscopes are generally costly equipment, limiting availability in remote areas

Can we make a high-quality microscope cheaply?

This paper makes that vision more real

With a cost below 350 euros, it delivers single-molecule sensitivity

Microscopy building day 7-9
First images and final checks

We finally have a working microscope 🔬

After installing the camera, we tackled hardware software communications using @micro-manager.bsky.social

Then we performed usual checks:
1) fluorescent marker
2) scale bar
3) bead solution (PSF)

How we analyze porous network @rochalab.bsky.social 🔬🧪

1) Adaptive thresholding
2)Distance map calculation
3)Watershed transformation
4)Quantification
5)3D rendering

✅ First, we used the reference laser to project a perfect vertical line through the center of the objective holder. We marked a target on the ceiling for future alignments, an easy trick to save time later

How do you ensure the optics are aligned straight when building a microscope?

For lasers, I often use diaphragms, but again, how do you ensure they are at the exact same height and lateral position?

Exciting times in @rochalab.bsky.social and @hofkenslab.bsky.social Lab !🧪We're restarting to build microscopes, and I decided to guide two PhD students (Steven Huysecom and Toon Van Roy) through the process.

First invited talk... and I missed my flight 😅✈️
What a wild 72h from 🇧🇪 to 🇸🇬!

Grateful to the organizers who reshuffled things so I could still speak — and even more shocked (and honored!) to get a prize for young speakers. 🔬🧪

Academia is a rollercoaster😅
Singapore, you were stunning 🌿💚

Amazing week at Göttingen University in Prof. @joergenderlein.bsky.social Lab with Toon & @sudiptaseth.bsky.social !

🔬 We performed high-res imaging of optoelectronic materials & collected 200GB+ of data!

Thanks to Oleksii Nevskyi & @nradmacher.bsky.social for their help we’ll be back! 🚀

✨ Great time at OPL 2024 in beautiful Valencia! ✨

Presented our work on Correlation Clustering Imaging (CLIM), exploring photophysics in perovskite solar cells. Chaired my 1st session, asking questions even outside my field, challenging!😅

Left with new ideas & contacts! First post on @bsky.app
