One recent obstacle to drug delivery research is an observed weak correlation between in vitro and in vivo performance. When nanoparticles are applied intravenously, they face several obstacles that differ from in vitro situations. Nanoparticles are usually covered by a biomolecular multilayer (a protein corona), which alters the physiochemical properties, pharmacokinetics, and toxicity profile of the nanoparticles. In Biophysics Reviews, researchers provide a cutting-edge characterization of the protein corona formed around nanoparticles and its impact on the physiochemical and biological properties of these nanoparticles.

Rapid, accessible and highly accurate detection of addictive substances such as opiates and cocaine is vital to reducing the adverse personal and societal impacts of addiction, something current drug detection systems can take too long to provide. However, on-site, real-time monitoring of abused drugs in a patient’s system could alert clinicians before dangerous levels are reached, and such an approach may not be far away.
