How heavy or how big can an object be before losing its quantum properties and obeying to the laws of classical physics? This question drives many research groups all around the globe. Answers still remain to be given as currently there are no systems which allow observing the expected tiny signatures of quantum effects in macroscopic objects.

Bacterial nanoinjectors transport proteins across three membranes: the inner and outer bacterial membranes plus the host cell membrane. Nanoinjectors essentially connect the bacterial cell contents with the host cell's and form a conduit for delivering bacterial effector proteins into the host. Once inside, these proteins reprogram the host's cellular functions to promote survival, growth, and bacterial propagation

Read moreUntil recently, scientists couldn't create the nanoparticles without producing synthetic chemicals that had negative impacts on the environment. A new method, created by a University of Missouri research team, not only eliminates any negative environmental impact, but also has resulted in national and international recognition for the lead scientist.

Read moreResearchers at the University of Illinois at Urbana-Champaign have developed a new process for making nanoparticles that relies on paclitaxel itself to serve as the initiator that triggers polymer synthesis. The result is not only a stable nanoparticle formulation of paclitaxel but also one with very high and very controlled amounts of drug being incorporated in the nanoparticle.

Read moreUsing a combination of polymers that respond to temperature, a research team at the University of Utah has developed a multifunctional nanoparticle that can image tumors using ultrasound and simultaneously deliver cell-damaging energy and anticancer drugs to those tumors. In addition, these nanoparticles appear to act specifically on tumors and not on healthy tissue.

Read moreIn an effort to overcome the drug resistance that often occurs in cancer, a team of investigators has developed a nanoparticle made of a blend of polymers that first releases a powerful anticancer drug and then delivers an agent that tricks a drug-resistant cell into committing suicide. Now, tests in mice with human breast cancer have shown that these blended nanoparticles are effective in maintaining high levels of both drugs in the vicinity of tumors.
