Mikroplastik hat sich zu einem globalen Umweltproblem entwickelt. Doch nicht nur die Polymere können für Lebewesen gefährlich sein. Angereicherte Metalle wie Chrom, Eisen oder seltene Erden können über das Plastik in die Organismen gelangen, wie Forscher des Helmholtz-Zentrums Hereon jetzt in einer Studie präsentiert haben.
Mikroplastik kann organische Schadstoffe aus der Umwelt anreichern und sie transportieren – das ist schon länger bekannt. Neu ist, dass auch Metalle auf diese Art und Weise transportiert werden kö .

Enzymes that can block HIV reactivation

Researchers at the
Indian Institute of Science (IISc) have developed artificial enzymes that can successfully block reactivation and replication of the Human Immunodeficiency
Virus (
cells.
According to IISc made from vanadium pentoxide nanosheets, these
nanozymes work by mimicking a natural enzyme called glutathione peroxidase that helps reduce oxidative stress levels in the host’s cells, which is required to keep the virus in check. “The advantage is that the nanozymes are stable inside biological systems and do not mediate any unwanted reactions inside the cells. They are also quite easy to prepare in the lab,” said Govindasamy Mugesh, Professor at the Department of Inorganic and Physical Chemistry.
