Application
AuNPs can be potentially immobilized on antibodies to improve the sensitivity of optical fiber sensors for the screening of COVID-19.[3] They can also be deposited on the titanium electrode for the formation of a miniaturized device for the electrochemical detection of DNA hybridization, which can be used in the diagnosis of COVID-19.[3]
Features and Benefits
- Negatively charged siRNA-PEG complex which is attached to positively charged GNPs is easily cleavable in reductive cytosolic environment thus enabling the release of siRNA into cytosol.
- Decreases the cytotoxicity and increases efficiency of GNPs. PEG increases the stability of the nanoparticles and prevents agglomeration.[4]
