Grow the microbes the petri dish never could.
Patented 3D hydrogels that rebuild the mucus and biofilm microenvironments your microbiota actually live in
Applications
From first culture to scale-up.
Fundamental research & biotic discovery
Culture the fastidious, low-abundance species standard media miss, and mine them for new biotics.
Next-generation prebiotics
Screen new substrates against a structured community and see which taxa they feed.
Efficacy testing for biotics
Test whether a strain survives, colonizes and outcompetes pathogens in its target mucus.
Pharmamicrobiomics
See how drugs and microbiota transform each other in a physiologically relevant matrix.
Permeability assessment
Measure how compounds and carriers cross mucus, the first barrier at any mucosal surface.
Beads for bioreactors
Nutrient-loaded beads that support recovery and yield of fastidious anaerobes in bioreactors.

of species present in native microbiota grew in Bac³Gel.
Oxygen gradients
Oxygen falls from surface to depth, so aerobes and anaerobes stratify as in mucus.
Viscoelastic structure
Mucus-like mechanics (G′ > G″) that shape adhesion, motility and biofilms.
Nutrient and chemical cues
Hydrate in NaCl, Mueller-Hinton, LB or your own medium: the cues microbiota need.
Ready to use
Sterile and ready out of the pack. Nothing to pour, set or autoclave.
High-throughput ready
Fits the plates and liquid handlers you already use. No anaerobic chamber.
Recoverable, quantifiable
Dissolve the gel to recover cells for CFU counts, sequencing or imaging.
Get started in 3 simple steps.
No specialized training or equipment needed: integrate Bac³Gel into your current workflow.



One platform, tuned to every mucosal niche.
Each screening tool reproduces the composition, structure and viscoelastic properties of a specific human mucus, so bacteria colonize, form biofilms and respond to drugs the way they do in the body. Pick the niche you study; the matrix comes standardized and ready to inoculate.


Lung³Gel
Recreates airway and cystic-fibrosis mucus with a physiological oxygen gradient. Models chronic P. aeruginosa and S. aureus lung infection and biofilm.

Vag³Gel
A vaginal-mucus microenvironment to study Lactobacillus dominance, dysbiosis and candidiasis, and to screen live biotherapeutics and antimicrobials.

Book an introductory callA patented, ready-to-use 3D hydrogel that reproduces the physical and chemical microenvironment of a specific human mucus or biofilm: oxygen gradients, viscoelasticity (G′ > G″), structure and nutrients. It ships standardized, in multi-well plates or syringes, so you inoculate and run without building a matrix yourself.
Aerobes, facultative anaerobes and strict anaerobes, including fastidious and low-abundance species that fail in standard 2D culture. The Universal Bac³Gel supports all ESKAPE pathogens (Gram-positive and Gram-negative), and the site-specific models are tuned to their native communities: gut, vaginal and airway.
Dissolve the gel with the Bac³Gel dissolution medium (50 mM sodium citrate) to release the cells intact. You can then perform CFU counts, 16S / shotgun sequencing, metabolomics or imaging, fully compatible with your existing workflow.
Yes. The biofilm-relevant matrix lets you determine MIC, MBC and MBEC, and run full antibiofilmograms against antibiotic panels and combinations. Because biofilm cells tolerate antibiotics far above the planktonic MIC, testing in 3D gives results that predict real-world performance.
The standardized multi-well plate format works with standard plate readers, and the gels are transparent enough for confocal and fluorescence microscopy to resolve 3D biofilm architecture in situ, with no need to disrupt the sample.
Yes, that is a core aim. By reproducing human mucus microenvironments in vitro, the models provide human-relevant data for colonization, permeability, efficacy and toxicity studies without animals, aligning with 3R and regulatory principles.
The matrix hydrates in NaCl, Mueller-Hinton, Luria-Bertani or your own medium of choice, so you keep the biochemical conditions your assay requires.
