The initiated Chemical Vapor Deposition (iCVD) technique is an all‐dry method for designing organic and hybrid polymers. Unlike methods utilizing liquids or line‐of‐sight arrival, iCVD provides conformal surface modification over intricate geometries. Uniform, high‐purity, and pinhole‐free iCVD films can be grown with thicknesses ranging from > 15 μm to < 5 nm. The mild conditions permit damage‐free growth directly on to flexible substrates, 2D materials, and liquids. Novel iCVD polymer morphologies include nanostructured surfaces, nanoporosity, and shaped particles. The well‐established fundamentals of iCVD facilitate the systematic design and optimization of polymers and copolymers. The functional groups provide fine tuning of surface energy, surface charge, and responsive behavior. Further reactions of the functional groups in the polymers can yield either surface modification, compositional gradients through the layer thickness, or complete chemical conversion of the bulk film. The iCVD polymers have been integrated into multilayer device structures as desired for applications in sensing, electronics, optics, electrochemical energy storage, and biotechnology. For these devices, hybrids offer higher values of refractive index and dielectric constant. Multivinyl monomers typically produce ultrasmooth and pinhole‐free and mechanically deformable layers and robust interfaces which are especially promising for electronic skins and wearable optoelectronics.This article is protected by copyright.

“…The lens surfaces were modified using the initiated chemical vapor deposition (iCVD) technique, offering several advantages. iCVD is not limited to flat surfaces or specific substrate materials and allows for uniform coating thickness without a loss of functionality, making it an ideal method for coating arcuated lens surfaces 22 . Previously reported studies on iCVD coatings for cell sheet engineering applications involve the modification of transfer surfaces 23 .…”

The field of corneal cell sheet engineering has evolved rapidly in the last decade; however, challenges related to transplantation into target tissue still exist, necessitating a new approach to integrate cell sheet technology onto a contact lens surface. In this study, a novel surface‐modified contact lens was developed for corneal regenerative medicine to ensure the easy and safe integration of cell sheets into the target tissue. The lens surface was coated with a thermo‐responsive polymer using the initiated chemical vapor deposition technique, facilitating the separation of tissue‐integrated cell sheets from the coated lens surface by simply lowering the temperature. BEAS‐2B and L929 cells, along with human limbal epithelial cells, were cultured on a crosslinked poly(2‐(dimethylamino)ethyl methacrylate)‐coated lens, providing temperature sensitivity for 14 days. At the end of the incubation period, the cultured cells were harvested as intact monolayer cell sheets through a simple temperature reduction, without enzymatic treatment or additional surgical procedures. Rapid and complete delamination of the cells planted and incubated on the coated lens surface was achieved at room temperature. Therapeutic contact lenses modified with cell sheet technology allowed targeted delivery of cells to the affected area of the cornea.
