A paper recently published in the journal ACS Omega reviewed the current status and potential of X-ray spectroptychography for the characterization of advanced nanomaterials. What is X-ray Spectroptychography? X-ray spectroptychography is an emerging technique that represents the ptychographic version of X-ray spectromicroscopy and is used for the chemical microanalysis of nanomaterials such as batteries and catalysts.

Inside a lab at the University of British Columbia, the printers aren't for paper. Instead, they are being used in hopes of producing something unexpected — sperm. "We wanted to really replicate what we see in the natural human body," Dr. Ryan Flannigan, a UBC urology assistant professor told Global News. In a pair [...]
Chronic kidney disease (CKD) is considered to be a global health crisis. A review on this topic has been submitted to the journal, Biomaterials and Biosystems, outlining the potential of using nanomaterials for the diagnosis and treatment of diabetic kidney disease (DKD). Diabetic Kidney Disease There are approximately 34.2 million people with diabetes within the [...]
A recent study submitted to the journal Chemosphere focuses on developing an electrochemical sensor for the sensitive detection of indinavir (IDV), an anti-retroviral HIV medication, by combining zinc oxide nanorods and molybdenum disulfide nanosheets on a screen-printed electrode. What is Indinavir (IDV)? Indinavir (IDV) is a drug used to treat the human immunodeficiency virus (HIV) that works [...]
A COVID-19 sensor developed at Johns Hopkins University could revolutionize virus testing by adding accuracy and speed to a process that frustrated many during the pandemic. In a new study published today in Nano Letters, the researchers describe the new sensor, which requires no sample preparation and minimal operator expertise, offering a strong advantage [...]
A group of researchers recently published a paper in the journal ACS Nano Letters that demonstrated the feasibility of using deep learning to simulate the post-fabrication appearance of nano/microstructures fabricated by focused ion beam (FIB) milling in the two-dimensional (2D) projection of a scanning electron microscope (SEM) image. FIB Milling Process and its Limitations FIB milling [...]
Evidence based medicine has been corrupted by corporate interests, failed regulation, and commercialization of academia, argue these authors The advent of evidence based medicine was a paradigm shift intended to provide a solid scientific foundation for medicine. The validity of this new paradigm, however, depends on reliable data from clinical trials, most of which [...]
Innovative research into DNA nanotechnology has been submitted to the journal, Nanomedicine: Nanotechnology, Biology and Medicine, comprising intelligent aptamer-incorporated DNA nanonetwork (Apt-Nnes). This novel technology can be used for imaging cancers as well as for increased drug delivery of chemotherapeutics. The Need for DNA Nanotechnology Nanoscale materials, which include materials that are within the nanoscale [...]
Researchers at Karolinska Institutet in Sweden have developed a novel strategy for identifying potent miniature antibodies, so-called nanobodies, against emerging SARS-CoV-2 variants. The approach led to the discovery of multiple nanobodies that in cell cultures and mice effectively blocked infection with different SARS-CoV-2 variants. The findings, which are described in the journals Nature Communications and Science Advances, [...]
Tiny quantum computing processors built from silicon have finally surpassed 99 percent fidelity in certain logic operations ("gates”). Quantum computers store information in the quantum state of a physical system (in this case, two silicon qubits) then manipulate the quantum state to perform a calculation in a manner that isn’t possible on a classical [...]
