May 15, 2024 (Nanowerk News) Researchers often study biomolecules such as proteins or amino acids by chemically attaching a “fluorophore,” a sensitive molecule that absorbs and re-emits energy from light. When activated by a laser and imaged through a high-powered microscope, these fluorophore tags or labels explode in a rainbow...
Self-assembling molecules enhance efficiency in solar cells
May 15, 2024 (Nanowerk News) Researchers from Kaunas University of Technology (KTU), Lithuania, who contributed to the development of record-breaking solar cells a few years ago, expanded their invention. The self-assembled monolayers can now be applied not only in inverted but also in regular structure perovskite solar cells. Their findings...
Scientists develop an affordable, chip-scale sensor for lead contamination
May 15, 2024 (Nanowerk News) Engineers at MIT, Nanyang Technological University, and several companies have developed a compact and inexpensive technology for detecting and measuring lead concentrations in water, potentially enabling a significant advance in tackling this persistent global health issue. The World Health Organization estimates that 240 million people...
1,000 times smaller than a grain of sand
May 15, 2024 (Nanowerk News) Reporting in the journal ACS Nano ("3D Printing of Glass Micro-Optics with Subwavelength Features on Optical Fiber Tips"), researchers at KTH Royal Institute of Technology in Stockholm say integrating silica glass optical devices with optical fibers enables multiple innovations, including more sensitive remote sensors for...
