We present herein the novel technique for constructing inverted cell-adhesion patternes on PEG gel modified glass surfaces by photoirradiation using the same photomask and materials. The PEG gel micropatterns were prepared by a photolithographic technique using a photomask with 100 microm aligned cavities after spin-coating of a mixed solution of alpha,omega-dimethacryloyl-PEG (PEG-DMA) and a p...

Spin-coating of chalcogenide glass is a low-cost, scalable method to create optical grade thin films, which are ideal for visible and infrared applications. In this paper, we study the influence of annealing on optical parameters of As(2)S(3) films by examining UV-visible and infrared spectroscopy and correlating the results to changes in the physical properties associated with solvent removal....

Here we propose an easy to build up and apply glass slide preparation system for single DNA molecules stretching. It is based on fast and simple coating of a solid glass with a cocktail of acrylic monomers that are easily polymerized via ultraviolet illumination. The acrylated slides are used to successfully stretch DNA molecules in a broader pH range compared to that of the commonly used amino...

The objective of our work is to improve the osseointegration of titanium (and its alloys) used in dental and orthopedic applications. To do this, we have been coating these metals with glasses whose compositions are based upon Bioglass®, which is a bioactive glass developed by Hench et al. Bioactive glasses have the property of forming an apatite layer (and therefore can chemically bond to bone...

Most microarray slides are manufactured or coated with a layer of poly(L-lysine) or with silanes with different chemical functional groups, for the attachment of nucleic acids on to their surfaces. The efficiency with which nucleic acids bind to these surfaces is not high, because they can be washed away, especially in the case of spotting oligonucleotides. In view of this, we have developed a ...

Functional glass surfaces with the properties of superhydrophobicity/or superhydrohydrophilicity, anti-condensation or low reflectance require nano- or micro-scale roughness, which is difficult to fabricate directly on glass surfaces. Here, we report a novel non-lithographic method for the fabrication of nanostructures on glass; this method introduces a sacrificial SiO2 layer for anisotropic pl...

BACKGROUND AND PURPOSE Cementless total hip arthroplasty is currently favored by many orthopedic surgeons. The design of the porous surface is critically important for long-term fixation. We examined the clinical and radiographic outcome of the cementless titanium hip implant with a bottom coating of apatite-wollastonite containing bioactive glass ceramic. METHODS We retrospectively reviewed ...

Maintaining cells in culture is essential for studying many aspects of cell biology and physiology. Cell culturing is dependent on proper anchorage of cells to the growth surfaces. For most cell lines, and especially for post-mitotic neurons, coated tissue culture plates are prerequisite for seeding. The most commonly used coating reagents are positively charged polymers such as poly-L-lysine o...

Optical properties and structure of antireflective coatings (AR) deposited from hydrolysed TEOS sol have been characterized in detail. The influence of various parameters on the formation of colloidal silica antireflective coatings by the dip-coating technique has been investigated. For the characterization of colloidal silica films, the UV-visible spectroscopy, laser ellipsometry, and atomic f...

We theoretically and experimentally demonstrated that the resonant wavelength of long period fiber gratings (LPG) could be shifted in a large magnitude by coating only nm-thick thin-film whose refractive index is higher than that of the glass cladding. The resonant wavelength shift results from either the variation of the thickness of the film and/or the variation of the refractive index of the...
