Advances in nanomedicine provide precise doses of antibiotics to fight infections and drug resistance
Credit: Drug Delivery and Translational Research (2024). DOI: 10.1007/s13346-024-01708-5 Researchers at the University of Waterloo have developed a new technology that keeps the entire dose of antibiotics in one small dose and allows a given patient to receive the amount of medicine they need to fight an infection on demand. did. This breakthrough in targeted medicine is the result of…

Harnessing magnetic relaxation: the “Pacman effect” allows precise organization of superparamagnetic beads
The orbital representation of a magnetic colloid dipole (left) resembles a Pac-Man shape (right). Credit: Biswal lab/Rice University Particles larger than ordinary molecules or atoms but invisible to the naked eye can form a variety of useful structures, including miniature propellers for microrobots, cell probes, and steerable microwheels designed for targeted drug delivery.

Citizen science collaboration provides precise data on exoplanet WASP-77 A b
Artist’s concept view of the WASP-77 A b system. Credit: NASA Exoplanet Catalog When a planet sways in front of its star, dimming the starlight we see, these events, called transits, provide a wealth of information about exoplanets orbiting stars other than the Sun. But without volunteers’ help, it’s hard to predict when these special events will occur. Fortunately, the…

Researchers develop new covalent organic framework for precise targeting of cancer treatment
Credit: ACS Applied Materials & Interfaces (2024). DOI: 10.1021/acsami.4c10812 A team of researchers at New York University Abu Dhabi (NYUAD), led by Chemistry Program Director Ali Trabolsi, has developed nanoscale covalent organic frameworks (nCOFs), crystalline organic polymers modified with peptides, to treat the most aggressive form of breast cancer called triple-negative breast cancer (TNBC). The peptides enable the COF to…
