Energy dependence of gold nanoparticle radiosensitization in plasmid DNA (2011)
Journal Article

Gold nanopa rticles (GNPs) are of considerableinterest for use as a radiosensitizer, because of their biocompat-ibility and their ability to increase dose deposited because oftheir high mass energy absorption coefficient. Their sensitizingproperties ha... Read More about Energy dependence of gold nanoparticle radiosensitization in plasmid DNA.

Intracellular mapping with SERS-encoded gold nanostars (2011)
Journal Article
Rodríguez-Lorenzo, L., Krpetic, Z., Barbosa, S., Alvarez-Puebla, R., Liz-Marzán, L., Prior, I., & Brust, M. (2011). Intracellular mapping with SERS-encoded gold nanostars. Integrative Biology, 3(9), 922-926. https://doi.org/10.1039/C1IB00029B

Here we report on the design, synthesis and application of small, highly bright, star-shaped SERS encoded single nanoparticles with the ability of providing an optical signal upon excitation with near infrared light. These particles are colloidally s... Read More about Intracellular mapping with SERS-encoded gold nanostars.

Acrylate-facilitated cellular uptake of gold nanoparticles (2011)
Journal Article
Krpetic, Z., Nativo, P., Prior, I., & Brust, M. (2011). Acrylate-facilitated cellular uptake of gold nanoparticles. Small, 7(14), 1982-1986. https://doi.org/10.1002/smll.201100462

Uptake of PEGylated gold nanoparticles by HeLa cells in the presence of acrylate is described. Nanoparticles that are usually not taken up readily cross the plasma membrane into the cytosol in the presence of acrylate. In addition, a method is descri...

Negotiation of intracellular membrane barriers by TAT-Modified gold nanoparticles (2011)
Journal Article
Krpeticc, Z., Saleemi, S., Prior, I., Sée, V., Qureshi, R., & Brust, M. (2011). Negotiation of intracellular membrane barriers by TAT-Modified gold nanoparticles. ACS nano, 5(6), 5195-5201. https://doi.org/10.1021/nn201369k

This paper contributes to the debate on how nanosized objects negotiate membrane barriers inside biological cells. The uptake of peptide-modified gold nanoparticles by HeLa cells has been quantified using atomic emission spectroscopy. The TAT peptide...
