Lighting up tumors with fluorescent nanoprobes
News from Nanowerk:

Posted: Nov 19, 2014

(Nanowerk News) A*STAR researchers have developed a hybrid metal–polymer nanoparticle that lights up in the acidic environment surrounding tumor cells (“Tumor-Responsive Fluorescent Light-up Probe Based on a Gold Nanoparticle/Conjugated Polyelectrolyte Hybrid”). Nonspecific probes that can identify any kind of tumor are extremely useful for monitoring the location and spread of cancer and the effects of treatment, as well as aiding initial diagnosis.
Cancerous tumors typically have lower than normal pH levels, which correspond to increased acidity both inside the cells and within the extracellular microenvironment surrounding the cells. This simple difference between tumor cells and normal cells has led several research groups to develop probes that can detect the low pH of tumors using optical imaging, magnetic resonance and positron emission tomography.

HUGHESVILLE, Md. (Nov. 13, 2014) — Approximately 7,500 families served by the Southern Maryland Food Bank will receive ENERGY STAR® certified compact fluorescent lights (CFL) as part of Southern Maryland Electric Cooperative’s (SMECO) participation in EmPOWER Maryland programs to help the state reduce energy consumption by 15 percent by 2015.

On November 6, 2014, SMECO donated 30,000 CFLs to the food bank. The CFLs will help Southern Maryland families facing economic hardship to reduce their energy costs so they can free up limited resources for other necessities.

“We know that some of our customer-members face hardships in paying their bills each month,” said Jeff Shaw, SMECO’s Energy and Technology Director. “Providing CFLs to these customer-members will help them reduce their energy usage, which reduces energy costs.
