Background In situation like diagnosis of clinical and forensic samples there exists a need
for highly sensitive, rapid and specific DNA detection methods. Though conventional DNA …

We report a novel method for rapid, colorimetric detection of a specific deoxyribonucleic acid
(DNA) sequence by carrying out a polymerase chain reaction in the presence of gold …

A major challenge in the area of DNA detection is the development of rapid methods that do
not require polymerase chain reaction (PCR) amplification of the genetic sample. The PCR …

Microorganisms belong to one of the biggest threats to humanity. Rapid detection and
identification of microbes in environmental, food and clinical samples is required for safety …

Background Gold nanoparticles have been widely employed for biosensing purposes with
remarkable efficacy for DNA detection. Amongst the proposed systems, colorimetric …

The development of an ultrasensitive biosensor for the low-cost and on-site detection of
pathogenic DNA could transform detection capabilities within food safety, environmental …

The contamination of heavy metals (eg, Hg, Pb, Cd and As) poses great risks to the
environment and human health. Rapid and simple detection of heavy metals of considerable …

We developed a novel strategy for rapid colorimetric detection of specific DNA sequence
based on gold nanoparticles assemblies induced by polymerase chain reaction (PCR) …

Gold nanoparticles (AuNPs) are well recognized tools for visual DNA detection. Most reports
on their use have however been restricted to synthetic or PCR amplified DNA sequences …

The growing interest in DNA diagnostics, especially in combination with the need for highly-
paralleled and miniaturized hybridization assays, is today addressed by fluorescence DNA …
