MicroSurfaces, Inc (MSI) develops surface coating technology for the rapidly growing microarray, microfluidics, and biosensor industries. The core of this technology is derived from MSI's proprietary chemical processes for the control and engineering of surface properties for immobilising biomolecules and in particular, proteins.

Proteins are the primary structural, functional and signalling elements in the human body, and therefore a comprehensive analysis of proteins is required to obtain a complete picture of normal and disease processes in the. MSI's surface coating chemistry allows the fabrication of next generation protein microarrays with exceptionally low background and excellent conformational control.

MSI provides functional coatings on glass slides, coverslips, silicon wafers, nanoparticles, and other surfaces for the immobilisation of biomolecules, including customised coating services.  MSI's glass slide has distinct advantages over current glass slides on the market.  This advantage is reflected in its exceptionally low background, high uniformity, and high chemical reactivity.  MSI has combined novel technologies from both surface chemistry and protein chemistry to create a class of high quality functional glass slides and surface modification technologies for microfluidic devices.

MSI also offer high throughput screening (HTS) services of compound libraries, drug candidates and nanoparticle-based medicine.  They specialise in the HTS of cell surface interactions in proteomics and glycomics analysis using their FluidArray® cell-membrane microarray platform.
