Gold nanoclusters for cancer nanomedicine

Gold nanoclusters can deliver drugs precisely to cancer cells without damaging healthy tissues. Using atomistic molecular dynamics simulations, researchers at the University of Jyväskylä Nanoscience Centre showed that the ratio of cancer-sensing and drug molecules is a critical parameter in optimizing the properties of gold clusters to maximize the probability of cluster adhesion to the surface of cancer cells.

Supercomputer Puhti vs. the Coronavirus: Review of CSC COVID-19 Fast Track Outcome

A total of 15 research projects were selected for the COVID-19 fast track. These projects have investigated the airborne transmission of coronavirus, searched for ways to inhibit virus replication, studied potential drug molecules and their structure-guided optimization, screened for potential drug candidates, studied virus mutations and identified virus variants through sequencing. Almost all of the thousands of coronaviruses detected from Finnish patients have been classified on Puhti supercomputer.
