Silver nanocubes enable nanolaser light generation

Physorg.com - 10 декабря, 2024 - 17:35
Kaunas University of Technology (KTU), Lithuania researchers, and scientists from Japan have developed a unique nanolaser. Although the dimensions of this laser are so small that its structure can only be seen through a powerful microscope, its potential is vast. With applications in early medical diagnostics, data communication, and security technologies, this invention could also become a key tool for the study of light and matter interactions.

Ultrasound-guided microscopic 'flower' particles show promise in targeted drug delivery

Physorg.com - 10 декабря, 2024 - 16:50
How can medicines be directed to precise locations within the body where they need to act? Scientists have been researching this question for a long time. An example would be delivering cancer drugs directly to a tumor so that they only take effect at a specific location, without causing side effects in the rest of the body. Research is under way to identify carrier particles to which active ingredients can be bound.

Novel mixture of mRNA in nanoparticles show therapeutic potential against tumor progression

Physorg.com - 9 декабря, 2024 - 20:51
Therapeutic mRNAs offer great potential as a versatile and precise tool against cancer and other diseases. However, the therapeutic effectiveness is limited by the poor translation uptake of naked mRNA. To circumvent this challenge, researchers from VIB, VUB, Ghent University, and eTheRNA Immunotherapies developed an immunotherapeutic platform based on lipid-based nanoparticles (LNPs).

Nanoparticle-mediated gene therapy fixes major cause of stillbirth and premature birth in guinea pig model

Physorg.com - 6 декабря, 2024 - 00:32
The life of billions of people inhabiting Earth is owed to a temporary organ that supported and nourished them in a mother's womb. The placenta, or afterbirth, is considered sacred by some cultures, its pivotal role in pregnancy recognized as far back as the raising of Egypt's pyramids. It provides nutrients and oxygen to the fetus via the umbilical cord, acting like a gut, kidney, liver, and lungs.

Experiments show coating rice seedling with nanoscale carbon dots from durian helps rice plants thrive in salty soil

Physorg.com - 5 декабря, 2024 - 21:32
Extreme weather and pollution have increased the salt content in some soil, making growing conditions harsh for salt-sensitive crops like rice. Now, researchers reporting in ACS Nano detail a possible solution that doesn't require genetic modification to make rice plants thrive in these conditions. In lab experiments, they determined that coating rice seedlings with magnesium-doped carbon dots—derived from durian peels—increased the seedlings' antioxidant activity and photosynthesis, reducing the stress caused by salty soil.
