A research team from Universität Hamburg and DESY has developed a new method to 3D print colloidal nanomaterials in the form of a so-called aerogel. This class of material is characterized by exceptional high porosity and opens versatile applications in catalysis, energy storage or sensor technology. In the journal Advanced Functional Materials ("Additive-Free, Gelled Nanoinks as [...]
A novel study published in the journal, Foods, describes edible nanoparticle-based antibacterial agents to control foodborne diseases. This research comprises a ternary nanoparticle with two active ingredients and a carrier material that was prepared from rosemary essential oil, nisin and Lycium barbarum polysaccharides. Using Edible Nanoparticles Interestingly, the use of functional nanoparticles with food-grade biological macromolecules [...]
Past infection with covid-19 does not necessarily confer protection against future infection, especially when it comes to the delta and omicron variants, researchers have warned. Wendy Barclay, head of infectious disease at Imperial College London, told an event organised by the Zoe study group1 on 3 February, “Each variant is different from the starting virus, [...]
A large multinational group of researchers has shown how the Omicron variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has gained exceptional immune evasion properties but also a much lower propensity to enter cells such as those in lung alveoli, resulting in its reduced pathogenicity. Their paper is currently released as an [...]
Researchers at ICMAB present a study on new nanovesicles, known as quatsomes, which have been successfully engineered to encapsulate and deliver microRNAs for the treatment of tumors. These nanovesicles are produced by a simple GMP compliant process, an unavoidable requirement for the clinical use of new drug candidates. The study, published in Small, has been [...]
A group of researchers recently published a paper in the journal Materials that demonstrated the viability of using vancomycin-functionalized gold nanoparticles (V-GNPs) against pathogenic bacterial strains. Background Antibiotic resistance among pathogenic bacteria is rising at a remarkable rate, which poses a significant risk to human health. For instance, vancomycin, a glycopeptide antibiotic, is typically used for [...]
Fabrication of materials using data-based techniques is being welcomed as a new strategy that will replace human scientists' hit and miss tests and labor demanding jobs. In an article published to the chemRxiv* preprint server, a Robotic Scientist framework that may provide unparalleled capabilities for logical design, retrosynthesis, and programmable fabrication of nanoparticles is discussed. The Robotic Scientist framework [...]
In a research study published recently in the journal Agriculture, an electrolytic sensor based on the concentration of floral nano-ZnO and the identification of immune reaction was created for the high-sensitivity monitoring of Tenuazonic acid (TeA) in fruit and vegetables. When comparing various morphologies, dimensions, and crystalline structures of nano-ZnO, the researchers discovered that floral [...]
The development of scaffold materials, such as nanoporous and nanofibrous hydrogel for biomedical applications, using green processes is a desirable approach. Natural biopolymers have been utilized for wound dressing, owing to their bioactive compounds content, mechanical properties, biodegradability, porosity, and proper surface chemistry. What is Silk Waste? Silk waste includes different types of raw [...]
Applications of Biosensors Biosensors can evaluate analytes in biological samples, allowing them to differentiate between diseased and healthy stages. On the other hand, several clinically useful biomarkers exist in biological samples in small amounts that need ultrasensitive biosensors to be measured. In recent years, biosensors with the ability to detect analytes at the single-molecule level have aroused [...]
