A simple way to control swarming molecular machines

Tue, 10/08/2019 - 12:24
The swarming behavior of about 100 million molecular machines can be controlled by applying simple mechanical stimuli such as extension and contraction. This method could lead to the development of new swarming molecular machines and small energy-saving devices.

Hydrogel paint - hydrogel coatings off the shelf

Tue, 10/08/2019 - 11:03
As a coating, hydrogels bring many advantages to regular solid surfaces, uniting the superior properties of the substrate with the superior properties of the hydrogel. However, making hydrogel coatings outside a laboratory environment can be difficult. Inspired by the economics of paint manufacturing, we have developed a technique for hydrogel coating preparation that breaks the process up into several steps. This step-wise synthetic pattern, decoupling polymerization from crosslinking and interlinking, divides the labor between the hydrogel coating maker and its user.

Graphene transistor catches mycotoxins in food

Fri, 10/04/2019 - 22:46
Researchers have developed a method for direct, point-of-use detection of mycotoxins in food. The method is based on the modification of electrolyte operated graphene filed effect transistors that have been specifically functionalized with aptamers by covalent binding. Demonstrating the performance of this method on Ochratoxin A, these sensors show a response time of within 5 minutes with a sensitivity down to 4 pg/ml - that is about three orders of magnitude less than accepted tolerance levels of Ochratoxin A.
