About Nanotools Bioscience
Pioneering optical stimulation and assays for RESEARCH with precision and scalability.


Nanotools Bioscience is at the forefront of developing graphene‑mediated optical stimulation (GraMOS) technology. Our innovative approach enables precise, non-genetic control of cellular function, revolutionizing high-throughput drug discovery.
We combine cutting-edge nanotechnology with advanced optical systems to create all‑optical assays that deliver physiological activation and precise readouts at unprecedented scales.
Our Science at a Glance
Graphene efficiently converts light into charge carriers on a femtosecond timescale. Near the cell membrane this creates a capacitive coupling that depolarizes cells without genetic modification — enabling precise, repeatable activation with simultaneous optical readouts.


Femtosecond hot‑carrier generation
Graphene turns photons into charge carriers without heating the lattice.
Capacitive coupling at the interface
Photo‑charges displace cations near the graphene/cell membrane boundary, shifting the transmembrane field.
Membrane depolarization → activity
Turning light on/off elicits transient depolarizations and triggers voltage‑dependent events.
All‑optical assays
Stimulation and readout with light — zero genetic modification required.
