Ultrasensitive, Label Free, Chemiresistive Nanobiosensor Using Multiwalled Carbon Nanotubes Embedded Electrospun SU-8 Nanofibers

This paper reports the synthesis and fabrication of aligned electrospun nanofibers derived out of multiwalled carbon nanotubes (MWCNTs) embedded SU-8 photoresist, which are targeted towards ultrasensitive biosensor applications. The ultrasensitivity (detection in the range of fg/mL) and the specificity of these biosensors were achieved by complementing the inherent advantages of MWCNTs such as ...

Multiscale carbon structures fabricated by direct micropatterning of electrospun mats of SU-8 photoresist nanofibers.

A novel method for the direct fabrication of arrays of micropatterned polymeric and carbon nanofiber structures on any substrate is developed. First SU-8, an epoxy-based negative photoresist, is electrospun under optimized conditions to produce a layer of polymeric nanofibers. Next, this nanofibrous mat is micropatterned using photolithography, and finally, pyrolysis produces ordered arrays of ...

Nonlinear Vibration Analysis of Embedded Multiwalled Carbon Nanotubes in Thermal Environment

In this article, based on the Euler-Bernoulli beam theory, the large-amplitude vibration of multiwalled carbon nanotubes embedded in an elastic medium is investigated. The method of incremental harmonic balance is implemented to solve the set of governing nonlinear equations coupled via the van der Waals (vdW) interlayer force. The influences of number of tube walls, the elastic medium, nanotub...

Label-free nucleic acid biosensors using carbon nanotubes

Single-wall carbon nanotubes (CNTs) belong to a unique class of one-dimensional nanostrcutures due to their all-carbon structure coupled with their very high aspect (at least 1000:1) and surface-tovolume ratios. Unlike bulk wires, charge variations on the surface of CNTs cause distinct changes in their electronic properties. These aspects make CNTs promising components for electrical biosensors...
