Degradable sugar-based polymers may store and release useful molecular freight — ScienceDaily

Degradable, bio-based polymers offer options for chemical recycling, and they can be a tool to store and release useful molecules. Scientists have developed a class of sugar-based polymers that are degradable through acid hydrolysis. The researchers also integrated “cargo” molecules in the polymer, which are designed to split off after polymer degradation. Degradable, cargo-bearing polymers […]

Engineers find antioxidants improve nanoscale visualization of polymers — ScienceDaily

Reactive molecules, such as free radicals, can be produced in the body after exposure to certain environments or substances and go on to cause cell damage. Antioxidants can minimize this damage by interacting with the radicals before they affect cells. Led by Enrique Gomez, professor of chemical engineering and materials science and engineering, Penn State […]

Scientists create polymers to detect banned substances in wastewater

Credit: SUSU Molecularly imprinted polymers, which have been created with the participation of a SUSU scientist, have become a base for a unique sensor that detects banned substances in wastewater. Police forces in European countries, where the problem of drug production is particularly acute, have shown interest in this development. The results of the research […]
