High Sensitivity DNA Detection Using Gold Nanoparticle Functionalised Polyaniline Nanofibres [PDF]
, 2010 Polyaniline (PANI) nanofibres (PANI-NF) have been modified with chemically grown gold nanoparticles to give a nanocomposite material (PANI-NF–AuNP) and deposited on gold electrodes. Single stranded capture DNA was then bound to the gold nanoparticles and

Crowding-induced hybridization of single DNA hairpins [PDF]
, 2015 It is clear that a crowded environment influences the structure, dynamics, and interactions of biological molecules, but the complexity of this phenomenon demands the development of new experimental and theoretical approaches.

RNA-programmed genome editing in human cells
eLife, 2013 Type II CRISPR immune systems in bacteria use a dual RNA-guided DNA endonuclease, Cas9, to cleave foreign DNA at specific sites. We show here that Cas9 assembles with hybrid guide RNAs in human cells and can induce the formation of double-strand DNA ...

Simplified detection of the hybridized DNA using a graphene field effect transistor
Science and Technology of Advanced Materials, 2017 Detection of disease-related gene expression by DNA hybridization is a useful diagnostic method. In this study a monolayer graphene field effect transistor (GFET) was fabricated for the detection of a particular single-stranded DNA (target DNA).

The process of infection with bacteriophage phiX174, XXX. Replication of double-stranded phiX DNA [PDF]
, 1969 Intermediates involved in the replication of double-stranded phiX174 RF DNA have been identified and partially characterized. Analysis of pulse-labeled RF DNA suggests that the synthesis of progeny RF molecules involves, in part, the addition of ...

Phase Transition of DNA-Linked Gold Nanoparticle
, 2002 Melting and hybridization of DNA-capped gold nanoparticle networks are investigated with optical absorption spectroscopy. Single-stranded, 12-base DNA-capped gold nanoparticles are linked with complementary, single-stranded, 24-base linker DNA to form ...
