With their special structure and large surface area, MOFs open up new opportunities in drug delivery. The ability to exchange the metal centers and organic linkers even provide an extensive library of MOF materials. As a result, the integration of small guest molecules within the MOF pores, such as small molecule drugs and biomolecules, have shown promise for delivery applications to treat diseases. A recent review article discusses current proceedings on integrating diverse biomolecules within MOFs.

Inspired by octopus arms, researchers demonstrate an uncomplicated and scalable templating technology for fabricating nanosuckers on PDMS substrates, using a scalable spin-coating technology. As the nanosuckers are pressed against a substrate, the flexible nanosuckers confirm to the substrate and deform by releasing the internal air between nanosuckers and the substrate, forming a seal and generating an adhesion force. The nanosucker adhesion is maintained over multiple contact cycles on both wet and dry surfaces.

Several research projects are working on reinventing the contact lens as a smart electronic device that, for instance, works as a self-powered biosensor for various point-of-care monitoring and wireless biomedical sensing. n addition to sensors, researchers are devising numerous applications for smart contact lenses, ranging from drug delivery systems to protection from electromagnetic wave damage. An application closer to contact lenses' original function, graphene can change the focal length of a polymeric soft contact lens in order to adjust near- and farsightedness.

Growing neurons outside the brain but with predictable synaptic connectivity between other neurons could provide for an efficient platform for fundamental research and design of neuroprosthetics. Various neuromorphic engineering research efforts are underway to do this. A team now has built a Brain-on-a-chip where they demonstrated guided growth of neurons on semiconductor nanowire scaffolds. Providing an environment were scientists could study a less complex neuronal circuit as opposed to a fully functioning circuit in a living mammalian brain will open up a new experimental paradigm of understanding how the neurons are influenced by the mechanical properties of the brain as they grow and form circuits.

Immunotherapy has become an important part of treating some types of cancer. It uses certain parts of a person's immune system to fight the cancer. Usually this is done by administering immune system components, such as man-made immune system proteins. In recent years, nanotechnology has played an increasingly important role in pursuing efficient vaccine delivery in cancer immunotherapy. This article discusses vaccine delivery by synthetic nanoparticles or naturally derived nanoparticles for cancer immunotherapy.
