Preparation of thin oligopeptide films using self-organized dendrimer monolayer as an anchoring scaffold
Functionalization of a self-organized poly(amidoamine) (PAMAM) dendrimer monolayer with oligopeptides on a silicon/quartz substrate is investigated in this paper. A monolayer of PAMAM dendrimers is formed on a silicon/quartz ...
Microstructure array on Si and SiOx generated by micro-contact printing, wet chemical etching and reactive ion etching
A method, combining micro-contact printing (μCP), wet chemical etching and reactive ion etching (RIE), is reported to fabricate microstructures on Si and SiOx. Positive and negative structures were generated based on ...
Controlled growth of peptide nanoarrays on Si/SiOx substrates
PAMAM dendrimer nanopatterns on Si/ SiOx substrates generated by dip-pen nanolithography are used as anchoring scaffolds for the growth of peptides in situ by ring-opening polymerization of tryptophan-N-carboxyanhydrides. ...
Dip pen nanolithography (DPN) : process and instrument performance with nanoInk's Nscriptor system
Precision nanoscale deposition is a fundamental requirement for much of current nanoscience research and promises to facilitate exciting industrial applications. Tailoring chemical composition and surface structure on the ...
Charge injection at carbon nanotube-SiO2 interface
Most single-wall carbon nanotube field-effect transistors show significant hysteresis in their transfer characteristics between forward and reverse gate bias sweeps. It was proposed that the hysteresis is due to a dynamic ...
Direct electrochemical reduction of single-layer graphene oxide and subsequent functionalization with glucose oxidase
A direct electrochemical method to reduce single-layer graphene oxide (GO) adsorbed on the 3-aminopropyltriethoxysilane (APTES)-modified conductive electrodes is proposed. The reduced GO adsorbed on glassy carbon electrode ...
