A low-tech way to create high-tech materials

AMOLF researcher Christiaan Van Campenhout has found a new, simple method to create a material with a regular pattern of crystalline bands. The pattern formed by the crystals is not a coincidence.

Growing cells on synthetic PIC gel could save millions of mice

The synthetic PIC gel, discovered in 2013 by Radboud University chemists, appears to behave like collagen. This makes the gel very useful for studying interactions between cells and their immediate environment. In practice, ...

Purification of DNA nanostructures from hydrophobic aggregates

Researchers in Japan have developed a new method for purifying cholesterol-modified DNA nanostructures that could be used to functionalize molecular robot bodies (lipid vesicles). The study was a collaboration between Yusuke ...

A new class of medicinal compounds that target RNA

A team of undergraduate and graduate chemistry students in Jennifer Hines' lab at Ohio University recently uncovered a new class of compounds that can target RNA and disrupt its function. This discovery identified a chemical ...

A gel (from the lat. gelu—freezing, cold, ice or gelatus—frozen, immobile) is a solid, jelly-like material that can have properties ranging from soft and weak to hard and tough. Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady-state. By weight, gels are mostly liquid, yet they behave like solids due to a three-dimensional cross-linked network within the liquid. It is the crosslinks within the fluid that give a gel its structure (hardness) and contribute to stickiness (tack). In this way gels are a dispersion of molecules of a liquid within a solid in which the solid is the continuous phase and the liquid is the discontinuous phase.
