Improving the sensitivity of Pedot:Pss modified gold electrode using gold and silver nanoparticles for Ganoderma boninense DNA detection

, , , ,
The sensitivity of a designed electrochemical DNA biosensor was improved using gold and or silver nanoparticles. A gold electrode modified with a conductive nanocomposite of poly(3,4-ethylenedioxythiophen)–poly(styrenesulfonate) (Pedot-Pss) and gold or silver nanoparticles enhanced the conductivity [...]

Substrate addition and matrix optimization increased sensitivity and selectivity of the PLGA sensor, resulting in a stronger detection signal toward bacterial contaminations

, , , , ,
The aim of this work was to contribute to the development of a simple and cheap biomimetic sensor, providing a higher sensitivity and selectivity toward microbiological contaminations. An optimization of the matrix of the optical [...]

Nephrotoxicity of Dextran Functionalized Graphene Nanoparticles and Their Potential as Magnetic Imaging Contrast Agents for Renal Abnormalities

, , , , , , , , , ,
Contrast-enhanced magnetic resonance angiography (MRA) employs the use of blood pool contrast agents (CA) such as gadolinium (Gd3+) complexes that allow for delayed phase arterial and venous imaging and improve the sensitivity in detecting small [...]
