Microchip factory tech could crack the secret code of cellular droplets
Why This Matters
Cells contain mysterious, membrane-free droplets that selectively pull certain proteins inside while keeping others out — and nobody knows quite why. Now, the same precision laser technology used to etch computer chips could be repurposed to build thousands of tiny molecular 'tollbooths' that measure proteins one by one as they pass through, revealing the hidden size, shape, and charge rules that grant or deny entry. If those rules can be decoded, it could open a new front against diseases like ALS and Alzheimer's, where proteins go rogue inside these very droplets.
