WILDLABS AWARD 2025 - Automatization of a Contact-Free Saliva Sampler for Wildlife Conservation

The WILDLABS AWARDS 2025 will enable our team - formed of the University of São Paulo (@mmcamar https://br.linkedin.com/in/maristela-martins-de-de-camargo-7bb9b75@swab_biosampler, https://sites.usp.br/swab/), the Yale University (@dzimmerman https://www.linkedin.com/in/dawnzimmerman1) and Eigen Strategies (@DeepakSathyanarayan https://www.eigenstrategies.com/https://www.linkedin.com/in/deepaksathyanarayan) - to advance conservation efforts by transforming our manual saliva collector prototype into a fully autonomous sample collector, significantly enhancing wildlife health monitoring. 

We aim to develop a device that autonomously collects salivary samples triggered by an approaching animal. The device will expose a fresh collection pad, capture video footage of animal interaction, detect saliva deposition, and store the licked cassette in an environment-safe compartment until retrieval, ensuring durability and safety even under rough handling by large carnivores.

By generating large, serial datasets, our device will support dynamic models for more accurate predictions of wildlife health outcomes, addressing urgent conservation challenges. 




This is exciting! Silly question, but how do you compel animals to engage with the device to the extent that they actually lick the collection pad? I'm imagining peanut butter isn't part of your technology stack. 

I eagerly await further information about the progress of this type of technology and its availability. I am a wildlife veterinarian with experience in handling and capturing wild carnivores, and this type of device would certainly facilitate epidemiological monitoring of elusive and logistically difficult-to-handle wildlife species.
