Polymeric Nano-Carriers with a Linear Dual Response Mechanism to Detect Disease

Technology Benefits

Potential advantages from molecular engineering linear dual-response mechanisms in the backbone of polymeric nanoparticles include enhanced stability and prolonged shelf life, while also increasing the response sensitivity and efficacy of targeted delivery to diseased environments. In addition, this polymeric nano-carrier technology may reduce overall toxicity by decomposing into easily excretable fragments.

Detailed Technology Description

Researchers from UC San Diego have designed ‘smart’ or ‘sensing’ nanoprobes (polymeric nano-carriers) responsive to pH and hydrogen peroxide stimuli, useful for amplifying contrast activation. Specifically, this technology comprises research designs and methods to deactivate and reactivate the contrast signal of magnetic resonance imaging (MRI) contrast agents and near infrared (NIR) contrast agents by the use of encapsulated dual response nano-carriers.
