State of the Art Synthetic Cells

FlowCyte synthetic cells simulate
important cell properties to give you the
most comprehensive cellular control

Revolutionary Technology

Slingshot Biosciences is at the forefront of advancing diagnostics and therapeutic development with "synthetic cells" that can match the optical, fluorescent, and biochemical features of any cell, in a shelf-stable, non-biohazardous and easily transportable format.

Combining proprietary chemistry and high precision, on-demand manufacturing, we offer an innovative, on-demand synthteic BioBank.

The result is a first-of-its-kind product that allows for single-step instrument calibration, assay controls, and diagnosis without the hassles that are associated with biological controls. Take your cell analysis, blood diagnosis, and cell therapy development standardization to the next level.


FlowCytes utilize a proprietary formulation model that can simulate the optical, biochemical and physical features of any cell. These parameters can be combined to  any cell-type/application, in record-time.
