Electrochemical transistors made of plastic open myriad possibilities. Since both electrons and ions are active, they can function as a bridge between traditional electronics and biological systems. A new dissertation from Linköping University in Sweden describes a simple and inexpensive humidity sensor that can be manufactured in a printing press.
Electrically conducting plastic is used today in field effect transistors, light-emitting diodes, electrochemical components, and batteries. Organic semiconductors are better than silicon because they can be applied to soft surfaces, even paper, using printing technology. What’s more, the components can be recycled in the same way as regular paper and plastic.
In an electrochemical transistor, both electrons and ions serve as charge bearers. It can be used in sensors, analytical tools, logical circuits, and smart displays. The current is controlled by a reduction/oxidation process, which means that it uses low-voltage current, roughly one volt, and is not dependent on small dimensions. Moreover, it has a memory function.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
