Description
Qiu and colleagues reviewed fluorescent probes modeled on green fluorescent protein, the glowing jellyfish protein that transformed cell biology, in a 2026 perspective. Instead of the whole protein, chemists copy its small light-emitting core, a molecule called HBDI, and tune it for sensing and imaging. The authors cover how these copies are made, how their structure controls their glow, and where they are being used.
Qiu highlights probes that switch on in response to specific biomolecules, report protein clumping linked to disease, map thickness of fluids inside cell compartments, and detect metal ions. The copies are easy to modify for color and targeting, yet they remain dimmer and less durable under light than classic dyes. Selective behavior inside messy living cells is still hard. The authors call for better synthesis routes and near-infrared versions that can image deeper into tissue.
