This paper presents the first systematic engineering study of the impact of chemical formulation and surface functionalization on the performace of free-standing microfluidic polymer elements used for high-pressure fluid control in glass microsystems. System design, chemical wet-etch processes, and laser-induced polymerization techniques are described, and parametric studies illustrate the effe...

Single-molecule fluorescence spectroscopy has proven to be instrumental in understanding a wide range of biological phenomena at the nanoscale. Important examples of what this technique can yield to biological sciences are the mechanistic insights on protein-protein and protein-nucleic acid interactions. When interactions of proteins are probed at the single-molecule level, the proteins or thei...

The growth, covalent functionalization, and subsequent DNA modification of gallium phosphide (GaP) nanorods is presented. Analysis of the nanorods by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD) revealed important information regarding their physical properties such as the presence of twinning defects. The nanorods were deposited onto g...

Effective surface functionalization plays a critical role in the selectivity and sensitivity of sensing devices. While chalcogenide glasses (ChG) have received lot attention as promising optical materials for mid-IR biosensors, there been just few reported instances their successful (bio)functionalization. In present work, we explore three different approaches grafting heterobifunctional deriva...

This paper reports the success of amino-functionalization on multi-walled carbon nanotubes (MWCNTs) to promote neuronal cells growth on MWCNT electrode for extracellular recording, attributed to the formation of positive charge of NH(2) molecules on their surfaces. Besides, the surface of MWCNT electrode becomes hydrophilic after amino-functionalization (AF-MWCNTs) which can enhance electrical ...

Composite materials based on epoxy matrix and single-walled carbon nanotubes (SWCNTs) are able to exhibit outstanding improvements in physical properties when using a tailored covalent functionalization with matrix-based moieties containing terminal amines or epoxide rings. The proper choice of grafted moiety and integration protocol makes it feasible to tune the composite physical properties. ...

Bioorthogonal ligation methods are the focus of current research due to their versatile applications in biotechnology and materials science for post-functionalization and immobilization of biomolecules. Recently, inverse electron demand Diels-Alder (iEDDA) reactions employing 1,2,4,5-tetrazines as electron deficient dienes emerged as powerful tools in this field. We adapted iEDDA in microcontac...

A stepwise surface functionalization methodology was applied to nanostructured ZnO films grown by metal organic chemical vapor deposition (MOCVD) having three different surface morphologies (i.e., nanorod layers (ZnO films-N), rough surface films (ZnO films-R), and planar surface films (ZnO films-P). The films were grown on glass substrates and on the sensing area of a quartz crystal microbalan...

This work demonstrates for the first time formation of nanogratings inside Barium Gallo-Germanate (BGG) glasses using femtosecond laser direct writing. These heavy oxide glasses, with a characterized transparency window up to 6 μm, along polarization sensitive birefringent nanostructures induced by laser, offer an excellent platform development mid-Infrared photonic applications. The fabricated...

choline oxidase (chox) was chosen as a model enzyme for evaluating the performance of cnts’ functional groups for development of enzyme electrodes. cnts were functionalized with carboxylic acid, amine or amide groups. carboxylic acid, amine and amide functionalized cnts were obtained by acid treatment, ethylenediamine or tetraethylenepentamine chemically modification and ammonia plasma treatmen...
