Abstract Polydopamine coating is a unique, simple, and substrate‐independent surface functionalization strategy. Techniques for secondary functionalization, patterning, re‐functionalization of polydopamine modified materials are important to broaden the scope applications such in variety fields. Here, facile strategy patterning presented. This approach combines advantages three methods: coating...

In the past decade, mesoporous silica nanoparticles (MSNs) with a large surface area and pore volume have attracted considerable attention for their application in drug delivery and biomedicine. Here we propose biosilica from diatoms as an alternative source of mesoporous materials in the field of multifunctional supports for cell growth: the biosilica surfaces were chemically modified by tradi...

We present a series of experiments to study the silanization of the silica surface of a fiber Bragg grating biosensor. A simple 4-layer attachment model is developed to describe the bonding of 3-aminopropyl triethoxysilane (APTES) or 3-aminopropylethoxydimethylsilane (APMDS) to the silica surface when both APTES and APMDS are dissolved in water or in pure ethanol. An adsorbed water layer is cre...

This paper presents systematic investigation on the surface properties of electroosmotic flows (EOF) inside microchannels for quartz, glass and PDMS based materials. Two novel methods to modify the surface properties of glass-based microchannels for capillary electrophoresis (CE) are developed. Instead of using complicated and time-consuming chemical silanization procedures for surface modifica...

We present a SU-8 based polymerase chain reaction (PCR) chip with integrated platinum thin film heaters and temperature sensor. The device is fabricated in SU-8 on a glass substrate. The use of SU-8 provides a simple microfabrication process for the PCR chamber, controllable surface properties and can allow on chip integration to other SU-8 based functional elements. Finite element modeling (FE...

This mini-review covers chelating sorbents anchored to silica gel and their analytical applications for the preconcentration, separation and determination of trace metal ions, focussing mainly on the last 20 years. The article summarizes also the experience gathered by our research group in the synthesis and characterization of new modified silica gels "via silanization", and their affinity tow...

This study was conducted to enhance the tensile bond strengths of resin cements to zirconia ceramics. Fifty-six zirconia ceramic specimens (Cercon Base) and twenty-eight silica-based ceramic specimens (GN-1, GN-1 Ceramic Block) were air-abraded using alumina. Thereafter, the zirconia ceramic specimens were divided into two subgroups of 28 each according to the surface pretreatment; no pretreatm...
