Different contribution of carbon nanotubes and graphene oxide in single nucleotide polymorphism for the diagnosis of human mad-cow disease

Choi W., Lee J-H., Luminescent MD, LLC, US

Rapid single nucleotide polymorphism (SNP) with 1,1’-oxalylimidazole chemiluminescence (ODI-CL) detection was developed for the early diagnosis of human mad-cow disease. Mutated single strand DNA (ssDNA) sequence discovered from patients having human mad-cow disease rapidly hybridize [...]

Engineering superhydrophobic and superoleophobic surfaces

Tuteja A., Choi W., Mabry J.M., McKinley G.H., Cohen R.E., Massachusetts Institute of Technology, US

The combination of surface chemistry and roughness on multiple scales imbues enhanced repellency to the lotus leaf surface when in contact with a high surface tension liquid such as water. This understanding has led to [...]

High Current Cold Electron Source Based on Carbon Nanotube Field Emitters and Electron Multiplier Microchannel Plate

Raghunandan S., Choi W., Florida International University, US

Vacuum microelectronics has been studied for decades to develop unique devices such as rf-generators, high efficiency flat panel displays, x-ray sources and so on. In recent years field emitters based on carbon nanotubes (CNTs) and [...]
