Abstract

We report an ultrasensitive DNA sensor using the rapid enhancement of electrocatalytic activity of DNA-conjugated Pd nanoparticles (NPs); the rapid enhancement results from the fast catalytic hydrolysis of NaBH(4) on Pd NPs and subsequent fast hydrogen sorption into Pd NPs.

6. Rational design of amphiphilic polymers to make carbon nanotubes water-dispersible, anti-biofouling, and functionalizable.

Author

Sangjin Park, Hae-Sik Yang, Dongkyu Kim, Kyungmin Jo, and Sangyong Jon

Subjects
POLYMERS, CARBON nanotubes, FOULING, FULLERENES
Abstract

We report rational design of amphiphilic polymers capable of making carbon nanotubes (CNTs) highly water dispersible and resistant to biofouling; such CNTs can be conjugated with bioactive molecules so as to be potential drug delivery vehicles. [ABSTRACT FROM AUTHOR]

7. Amperometric immunosensing using an indium tin oxide electrode modified with multi-walled carbon nanotube and poly(ethylene glycol)–silane copolymer.

Author

Md. Abdul Aziz, Sangjin Park, Sangyong Jon, and Haesik Yang

Subjects
ELECTROCHEMICAL analysis, TIN, SILANE, COPOLYMERS
Abstract

We describe a sensitive electrochemical immunosensor that takes advantage of the low background current of an indium tin oxide electrode, the good electrocatalytic properties of multi-walled carbon nanotubes, and the low biofouling properties of poly(ethylene glycol)–silane copolymer.
