Ultrasensitive mercury sensors based on graphene decorated with nanoparticles

Ayesh A.I., Qatar University, QA

In this work we present a highly sensitive and selective sensor for detection of mercury traces in water. The sensor is constructed by creating interdigitated metal electrodes on a graphene layer placed on SiO2/Si substrate. [...]

Application of chemiluminescent resonance energy transfer and graphene sheet for the rapid quantification of mercury in a sample

Kwon M., Park Y., Lee J-H., Lee S-Y, Kim Y.T., Lee J-H., Lee S-Y, Luminescent MD, LLC, US

Using intra chemiluminescent resonance energy transfer (CRET) between DNA aptamer and fluorescein and physical property of graphene sheet, cost-effective and simple biosensor was developed for the rapid quantification of Hg2+ in a sample. The limit [...]

Relaxation Time Constants of Nanometals in Human Tissues and Clinical Applications

Sharma A., Sharma R., Sharma A., Sharma R., Center of Nanotechnology, IN

The metals are in abundance in human body in biofluids, blood, cerebrospinal fluid, saliva, lymph. These metals are found in free and bound forms in each tissue and their amount is tissue specific. The mechanism [...]

Extended Applications of Picomolar Technology to Measure Immunoactive Biomarkers

Shriniwas B.D., Sharma A., Sharma R., Sharma A., Sharma R., RTM Nagpur University, IN

The picotechnology extended use in marine and biology applications are reported after our report on picotechnology to measure picomolar quantities of single stranded DNA in evaluation of Texotere chemosensitivity (TCRT,2008,28(6):175). Lead and mercury poisoning is [...]

Manufacturable, Highly Responsive Nanowire Mercury Sensors

Keebaugh S., Nam W.J., Fonash S.J., The Pennsylvania State University, US

We have developed a manufacturable and highly responsive gold nanowire sensor capable of detecting ppb concentrations of mercury in air and water. The nanowire sensor exhibits a superior response compared to thin film sensors and [...]
