Quantum dots, a phenomenon in quantum physics that alters the energy of electrons and changes the properties of particles, caught the attention of the Royal Swedish Academy of Sciences (KVA) for the 2023 Nobel Prize in Chemistry. Alexei Ekimov and Louis Brus received the award for their discovery; Moungi Bawendi, for developing its applications. With their work, “in equal shares,” said the Secretary General of KVA Hans Ellegren, the three scientists have laid the foundations of nanotechnology, a tool that we see today in our homes, on televisions and LED lamps, or in laboratories and hospitals for designing new drugs or new strategies against cancer.
Researchers from The Hong Kong Polytechnic University (PolyU) said they have used two-dimensional nanosheets (FePSe3) to develop a biomimetic nanosheet that can monitor tumor development, treat tumors and monitor the treatment progress in real-time. With positive results from mice, the team hopes to further test it on larger animals, then move on to clinical studies.
Two decades after the federal government jumpstarted U.S. R&D investment in its understanding and control of nanoscale matter, funding for the efforts across the government reached about $1.4 billion in fiscal 2020, part of a total cumulative investment of about $29 billion. Though FDA-budgeted nanotech research has accounted for just a fraction of that, at a modest $133 million since 2009, substantial advances have still been made, according to a presentation on the state of nanotech progress and innovation issued this summer.
Monitoring the electrical activity within and between cells on a large scale in a living animal may seem like a task that's next to impossible. But that's precisely what researchers at Cambridge, Mass.-based Harvard University aim to do with the next iteration of nanoscale sensors in the shape of wires.
