A method to functionalize single-walled carbon nanotubes (SWNTs) in a field-effect transistor (FET) device for the selective detection of heavy-metal ions is presented. In this method, peptide-modified polymers were electrochemically deposited onto SWNTs and the selective detection of metal ions was demonstrated by choosing appropriate peptide sequences. The signal transduction mechanism of the...

Polyimide is one of the most popular substrate materials for the microfabrication of flexible electronics, while polydimethylsiloxane (PDMS) is the most widely used stretchable substrate/encapsulant material. These two polymers are essential in fabricating devices for microfluidics, bioelectronics, and the internet of things; bonding these materials together is a crucial challenge. In this work...

this study is about complexes of li doped silicon carbide nanotube with thymine and cytosine ingas phase and aqueous solutions. li doped silicon carbide nanotube and its pyrimidine nucleobasecompounds were first modeled by quantum mechanical calculations in gas phase and in water.calculated binding energies indicated the stronger ability of thymine to functionalize silicon carbidenanotube than ...

A synthetic sequence has been developed to selectively functionalize the furan ring of the natural product salvinorin A (2a). The synthetic routes described convert the furan ring in 2a into an N-sulfonylpyrrole, oxazole or an oxadiazole. In addition, a procedure has been found to remove the furan skeleton completely. Biological results indicate that replacement of the furan ring with an N-sulf...

Here we present a hybrid approach to functionalize multi-walled carbon nanotubes in aqueous solution, exploring a non-covalent binding strategy. We focus on formation of hybrid complexes consisting of carbon nanotubes decorated by single stranded DNA, non-covalently attached using surfactants as intermediate layers. Unlike single walled carbon nanotubes, revealing easy side wall wrapping of DNA...

Cold plasma conditions offer a novel route for synthesizing and depositing macromolecular structures on various organic and inorganic surfaces, and to functionalize in a controlled manner even the most inert polymeric substrates. The energies of active species of plasma are high enough to split all chemical bonds from organic and organometallic derivatives and consequently, tailored macromolecu...
