How it Works

Print thousands of microwells.
Watch every clone. Recover what matters.

TROVO combines hydrogel microwell printing, longitudinal live-cell imaging, AI-assisted analysis and light-induced cell recovery in one benchtop system.

Step 01

Print

Turn your standard culture plate into thousands of individual experiments.

TROVO uses light-based hydrogel lithography to print customizable microwells directly onto standard cell culture plates. No new proprietary plate formats. No microfluidics. The printed array can go straight into an incubator like any culture plate.

Standard labware compatibility

Works with commonly used plates and slides โ€” no proprietary formats required.

Any size or shape

Round, square or custom microwell geometry configured to your assay.

Biocompatible PEGDA hydrogel

Inert, non-toxic walls compatible with standard reagents and matrices.

Shared culture medium

At 200 ยตm walls, medium, oxygen and cytokines remain freely accessible.

Step 02

Discover

Watch what your cells actually do.

TROVO automatically images the full microwell array at defined timepoints โ€” fluorescence and brightfield โ€” creating a time-course record for thousands of individual co-cultures instead of averaging across a full population.

Cytotoxicity

Per-microwell tumor killing over time.

Persistence

Identify clones that keep killing after one interaction.

Proliferation

T cell expansion measured alongside tumor killing.

Exhaustion

Longitudinal decline in killing activity.

Secretion

Fluorescent readout for secreted antibodies or cytokines.

Migration

Cell movement within and across microwell boundaries.

Why longitudinal tracking matters

Flow cytometry gives a snapshot. Bulk imaging gives population averages. TROVO tracks the same microwells over the full assay duration โ€” generating a complete behavioral history for every clone.

Native controls via Poisson seeding

At the right seeding density, Poisson statistics naturally populate the array with T-cell-only, tumor-only and co-culture wells across a range of E:T ratios โ€” creating matched internal controls on the same plate for Z-score-based ranking.

Step 03

Retrieve

Recover the cells that earned it.

After imaging identifies microwells of interest, TROVO uses a light-induced capture gel to selectively encapsulate target populations in place. Unwanted cells are washed away; the gel is dissolved enzymatically, releasing viable recovered cells.

    How capture works

    1

    A liquid, biocompatible capture gel is applied across the plate surface.

    2

    TROVO projects a 405 nm laser through an LCD screen beneath the plate โ€” polymerizing the gel only in selected microwells.

    3

    The plate is washed, removing all uncaptured cells.

    4

    The solidified gel containing selected populations is enzymatically dissolved, releasing viable cells into solution.

Behavioral selection

Cells are recovered based on observed function โ€” not predicted phenotype or predefined markers.

No physical stress

No high-pressure fluidics, no droplet generation โ€” preserving viability and transcriptome integrity.

Flexible compatibility

Recovered populations feed directly into NGS, expansion, re-challenge, direct-to-PCR or single-cell analysis.
