Who We Are

Bringers of high-speed 3D vision

Holloid brings the benefits of high-speed 3D imaging and optical characterization to the market in order to detect, identify and sort colloids, such as dispersed particles, cells, and microorganisms, by innovative hardware and software solutions.

We provide our unique new technology as a service while we develop tailor-made equipment and application solutions for our future customers. 


Our Innovative Technology

See what you have not seen yet

Holloid offers a novel type of microscope/cytometer and an associated label-free technique that provides image-based data on colloids. This technique does not require a priori assumptions while providing statistics on individual objects. 

Holloid provides real-time multi-dimensional data on physical characteristics. We can quantify the following physical properties in-real-time for all objects:

  • Static properties (require snapshots only):

    • number

    • size

    • shape

    • eccentricity

    • amount of scattered light (dry mass)

    • inner structure (of cells: centrosome, inclusion bodies, etc.)

  • Dynamic properties (require multi-image acquisition, “movies”):

    • translational diffusion (hydrodynamic size)

    • rotational diffusion (asymmetric objects)

    • sedimentation rate (density)

    • interaction potentials

including motion and interactions, of cells and other colloids, based on 3D imaging, with the throughput of cytometry.
