Turning a dangerous toxin into a biosensor

Some types of bacteria have the ability to punch holes into other cells and kill them. They do this by releasing specialized proteins called "pore-forming toxins" (PFTs) that latch onto the cell's membrane and form a tube-like ...

Scientists develop DNA microcapsules with built-in ion channels

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 ...

Graphene layer enables advance in super-resolution microscopy

Researchers at the University of Göttingen have developed a new method that takes advantage of the unusual properties of graphene to electromagnetically interact with fluorescing (light-emitting) molecules. This method allows ...

Study unravels mystery of antimicrobial frog secretions

Japanese scientists, including researchers at Tokyo University of Agriculture and Technology (TUAT) and Yokohama National University, have identified the molecular mechanism that gives the skin secretions of a species of ...

Biosensor may provide better cancer diagnosis

Lawrence Livermore National Laboratory (LLNL) researchers have developed a new biological sensor that could help clinicians better diagnose cancer and epilepsy.

Nano-bio-computing lipid nanotablet

Nanoparticles can be used as substrates for computation, with algorithmic and autonomous control of their unique properties. However, scalable architecture to form nanoparticle-based computing systems is lacking at present. ...

A novel approach for the study of integral membrane proteins

The membranes that surround our cells contain a large number of proteins. Membrane proteins are therefore a crucial class of macromolecules in living systems. They play key roles, such as providing transport gateways into ...

Assembly of fluctuating molecules in artificial cell membrane

Lipids and membrane proteins existing in cell membranes, which are located at the outermost layer of cells, are responsible for recognizing extracellular environments and transferring that information inside the cell. Due ...
