A Research group led by Tokyo Tech reports a way of constructing DNA-based microcapsules that hold great promise for the development of new functional materials and devices (Figure 1). They showed that tiny pores on the surface of these capsules can act as ion channels. Their study will accelerate advances in artificial cell engineering and molecular robotics, as well as nanotechnology itself.

DNA-based, self-assembled nanostructures are promising building blocks for new kinds of micro- and nanodevices for biomedical and environmental applications. Much research is currently focused on adding functionality to such structures in order to expand their versatility.

Example - Capsules - Liposomes - Membrane - Sensors

For example, engineered capsules called liposomes that have a lipid-bilayer membrane are already successfully being used as sensors, diagnostic tools and drug delivery systems. Another group of capsules that do not have a lipid bilayer but are instead composed of colloidal particle membrane, known as Pickering emulsion or colloidosomes, also have potential for many biotechnologically useful applications.

Now, a research group led by...
