Watching how proteins form droplets and clumps inside living cells
Probing Biomolecular Condensates in Live Cells using Microsecond-scale Single Molecule Rotational Diffusion Microscopy (µs-SiMRoD)
This project uses a new ultra-fast microscope to watch tiny protein droplets form and harden inside cells, work that could help people with Alzheimer's and related brain diseases.

What this research studies
Researchers will use a microsecond-scale single-molecule rotational diffusion microscope to image biomolecular condensates — tiny liquid-like droplets that form inside living cells. They will record how these droplets move, change their fluidity, and sometimes transition into solid aggregates that can harm cells, using cultured cells and labeled proteins in the lab. The experiments focus on proteins linked to neurodegenerative diseases, connecting the physical behavior of condensates to processes seen in Alzheimer's and related disorders. This is laboratory-based work rather than a clinical trial, but its findings could guide future therapies to prevent or reverse harmful protein clumps.
Who could benefit from this research
Good fit: This project does not enroll patients; it is a laboratory imaging study using cell models rather than people.
Not a fit: People seeking immediate treatments or clinical interventions should not expect direct benefits from this lab-based research.
Why it matters
Potential benefit: If successful, the work could reveal early steps of harmful protein clumping and point to new targets for therapies to slow or prevent Alzheimer’s-related brain damage.
How similar studies have performed: Other groups have imaged biomolecular condensates with conventional microscopy and found links to disease, but applying microsecond single-molecule rotational diffusion imaging in live cells is a novel and largely untested approach.
