Single carbon nanofibers (CNFs) grown on the tips of scanning probe microscopy (SPM) cantilevers by Arþ irradiation attract much attention, because of their potential in the batch fabrication of CNF probes. Here, we first revealed their mechanical characteristics. An excellent flexibility of CNF probes was confirmed by hard-contact examination (force-curve measurement) in which the cantilever w...

A previously proposed two-terminal carbon-nanotube-based device with closed-loop feedback is demonstrated through in situ scanning electron microscopy (SEM) experiments. The pull-in/pull-out tests were carried out using a multi-walled carbon nanotube (MWCNT) welded to a conductive probe attached to a nanomanipulator. The MWCNTs were cantilevered over a gold electrode and electrostatically actua...

An all-optical ultrasound probe for vascular tissue imaging was developed. Ultrasound was generated by pulsed laser illumination of a functionalized carbon nanotube composite coating on the end face of an optical fiber. Ultrasound was detected with a Fabry-Pérot (FP) cavity on the end face of an adjacent optical fiber. The probe diameter was < 0.84 mm and had an ultrasound bandwidth of ~20 MHz....

Giant random telegraph signals sRTSsd are observed in p-type semiconducting single-wall carbon nanotube sSWNTd field-effect transistors sFETsd. The RTSs are attributed to the trapping and detrapping of the two defects inside SiO2 or in the interface between SWNT and SiO2. The amplitude of the RTSs is up to 60% of total current. The giant switching amplitude of RTSs is believed to be caused by t...

Dynamic atomic force microscopy (dynamic AFM) with carbon nanotube tips has been suggested as an enabling tool for high precision nanometrology of critical dimension features of semiconductor surfaces. We investigate the performance of oscillating AFM microcantilevers with multi-walled carbon nanotube (multi-walled CNT) tips interacting with high aspect ratio structures while in the attractive ...

to investigate the interaction and adsorption of drug and carbon nanotube on human serum albumin, three anti-cancer drugs ([pd(phen)(r-gly)]no3, r = methyl, propyl and amyl) with different hydrophobic tails and anticancer activities were selected. these drugs have better anti-tumor activity and less side effects than that known cis-platinum drug. human serum albumin is also important for drug d...

In an attempt to give a brief introduction to carbon nanotube inkjet printing, this review paper discusses the issues that come along with preparing and printing carbon nanotube ink. Carbon nanotube inkjet printing is relatively new, but it has great potential for broad applications in flexible and printable electronics, transparent electrodes, electronic sensors, and so on due to its low cost ...

Carbon nanotubes (CNT) were synthesized on heated scanning probes and under ambient conditions without requiring Chemical vapor deposition (CVD) apparatus or process gases. In this study, dip pen nanolithography (DPN) techniques were utilized for deposition of catalyst precursors on the scanning probe tips in the form of aqueous solution of metal salts--prior to the synthesis of the CNT. A laye...
