Researchers in the cancer nanomedicine community debate whether use of tiny structures, called nanoparticles, can best deliver drug therapy to tumors passively — allowing the nanoparticles to diffuse into tumors and become held in place, or actively — adding a targeted anti-cancer molecule to bind to specific cancer cell receptors and, in theory, keep the nanoparticle in the tumor longer. Now, new research on human and mouse tumors in mice by investigators at the Johns Hopkins Kimmel Cancer Center suggests the question is even more complicated.

Scientists are working on ways to build atomic structures to specifications and are studying these methods on a larger scale using ‘big atoms.’ These ‘big atoms’ are micro-particles of silica mixed into liquid crystals. Silica particles, when mixed into liquid crystals, can act a lot like individual atoms. The geometry of the particles determines how they interact with each other the same way the electrons around an atom determine how it interacts with other atoms. Scientists can observe interactions in these ‘big atoms’ with optical microscopes, removing the need for atomic-scale imaging.
