Market Opportunity

The ability to tailor enhancement and inhibition of cellular interactions on inorganic surfaces has not only important for scientific understanding, but for in-vitro (cell culture and flow cytometry/ microfluidic) and in-vivo (implants or device utilization) applications as well. Weak cell-surface adhesion to substrates is a common problem and presents technical limitations to the design of experiments; on the contrary, extensive adhesion of cells to surfaces that that should be free of cells (for example on retinal implants, heart valve implants, etc.) is also a problem.


This technology relates to an inorganic thin film coating which can be applied onto glass surfaces (such as glass slides,  coverslips, implant surfaces, etc), thereby enabling the  to direct/enhancement / inhibition of mammalian cell adhesion, proliferation and differentiation.

Figure 1: Primary human keratinocytes adhere onto the whole control wafer. But on the coated substrate (with varying composition), keratinocytes begin to adhere around the substrate coated at a certain composition.


Figure 2: Primary human fibroblasts adhere onto the whole control wafer. But on the coated substrate (with varying composition), fibroblasts begin to adhere on the substrate coated at a certain composition

Figure 3: Increase in mature lipid forming differentiated adipocytes is observed on the coated wafer as opposed to the control wafer without coating
