Renasco

Renasco is a surface-engineering company specializing in nanoparticle characterization and functionalized glass substrates for diagnostics, cell biology, nanomedicine, and related research. Its products combine cold-plasma technology with controlled surface chemistries to support reproducible testing, advanced surface studies, and scalable manufacturing.

The company’s Nanoparticle Hydrophobicity Collector is a microfluidic chip on a glass slide, manufactured under licence from the European Commission’s Joint Research Centre. Designed for OECD Test Guideline 126, it uses three engineered surfaces and real-time dark-field microscopy to measure nanoparticle binding rates and determine a hydrophobicity index. The ready-to-use collector is intended to deliver consistent results across production batches and laboratories.

Renasco also supplies coated and functionalized glass slides, with organic and inorganic coatings and surface groups such as epoxide, amine, and carboxylic acid. Its plasma-based treatments are dry, low-temperature, and solvent-free, and can be configured for flat substrates or complex three-dimensional structures. Customers can request standard or customized surface chemistries and slide designs, with support ranging from early prototyping to serial production.
