The #nanotechnology_standard (ISO 21363:2020) provides detailed instruction on how to calibrate, capture, measure, and analyze #TEM images to obtain particle size and shape distributions in the #nanoscale.
#Ferumoxides are composed of superparamagnetic #iron_oxide covered with a layer of #dextran with a hydrodynamic diameter is about 80-150 nm, for intravenous administration as an #MRI contrast agent.
Around 30 percent of #nanodrugs are #antineoplastic agents used to control and kill neoplastic cells or to prevent and inhibit the development of #tumors.
More than 40% of #nanotechnology_publications have been published by Chinese researchers in 2021. Iran, Saudi Arabia, and India have the largest amounts of #Local_Share.
The ISO #nanotechnology_standard (ISO/TS 21356-1) specifies the sequence of methods for characterizing the structural properties of #graphene including the number of layers, thickness, the lateral flake size, the level of disorder, and the specific surface area.
Among various types of emerging #solar_cells, the ones based on #perovskite have been the fastest to reach higher efficiencies, holding great promise for facile and low-cost production of solar cells.
The first #FDA-approved #nanoliposomal drug is #liposomal #doxorubicin which employs 100-nm liposomes modified by #polyethylene_glycol (PEG) chains, using the PEGylation process.
The newly published Danish #nanotechnology_standard can be used to evaluate #nano_objects generated as products of degradation, wear, or from mechanical treatment processes from #medical_devices manufactured not using #nanomaterials.
#South_Africa has the highest #international_collaboration in publishing #nano_articles with #India, followed by the United States. But in recent years, this collaboration has shifted more towards other African countries.
The recently published #nanotechnology_standard of #ASTM focuses specifically on fiber-based constructs for tissue-engineered medical products.
#Claytronics is the product of the convergence of #nanotechnology and #information_technology. Such materials would be composed of #catoms which would be the smallest indivisible units of the #programmable_matter.
The #Spectradyne nCS1 is a particle analyzing instrument that uses #microfluidic resistive pulse sensing rather than optical measurements to determine the concentration and size of samples. #nanotechnology_standard
#Nanobodies are able to access #epitopes that are inaccessible to conventional #antibodies. It should be possible to develop nanobodies that recognize novel epitopes that retain broad neutralizing activity.
19 #nanotechnology_standards were published during the first quarter of 2021, 8 of which are related to test methods and characterizations.
#Centrifugal_spinning that utilizes centrifugal force instead of high voltage to produce polymer nanofibers has been suggested as a safer and more cost-effective alternative to #electrospinning.
About 14 #nanotechnology_patents (USPTO+EPO) per 100 #nano_articles in 2020: USA, Japan, and Taiwan have the highest ratio.
Near to 15 #nanotechnology_patents were registered with USPTO and EPO in 2020, for every 100 WoS indexed #nano_articles. The United States leads the way with a rate of about 52.
About 3 percent of the total patent applications filed with the #USPTO and #EPO in 2020 are related to nanotechnology; while the ratio is about 9% for #nano_articles.
#Vietnam had significant progress in publishing #nano_articles in 2020. Around 17 percent of Vietnam's scientific publications had been related to nanotechnology.
Microorganisms such as microalgae, yeasts, #fungi, #bacteria, and even #viruses can be utilized as biofactories to produce single and multi-element #inorganic_nanomaterials under mild conditions.
