The diameters of nanofibers depend on the type of polymer used and the method of production. [5] All polymer nanofibers are unique for their large surface area-to-volume ratio, high porosity, appreciable mechanical strength, and flexibility in functionalization compared to their microfiber counterparts.

When the balloon is inflated the carbon, nanofibers penetrate diseased cells and delivery therapeutic drugs. Researchers at MIT have used carbon nanofibers to make lithium-ion battery electrodes that show four times the storage capacity of current lithium ion batteries. Researchers are using nanofibers to make sensors that change color as they ...
Polyaniline nanofibers have been shown to be incredibly successful as chemical sensors, as they perform better than conventional polyaniline films in numerous tests. [11] This performance difference has been attributed to their high surface area , porosity , and small diameters which enhance diffusion of materials through the nanofibers.
Carbon nanotubes have furthermore been grown inside microfluidic channels for chemical analysis, based on electrochromatography. Here, the high surface-area-to-volume ratio and high hydrophobicity of CNTs are used in order to greatly decrease the analysis time of small neutral molecules that typically require large bulky equipment for analysis.
He used an ultramicroscope that employs a dark field method for seeing particles with sizes much less than light wavelength. There are traditional techniques developed during the 20th century in interface and colloid science for characterizing nanomaterials. These are widely used for first generation passive nanomaterials specified in the next ...
Nanofibers are key to the story and outcome of '3 Body Problem,' Netflix's major new sci-fi series. ... —Auggie's nanofiber technology is essentially used as an invisible, razor-sharp lattice ...
The starch nanofibers have advantages over other materials, Clancy noted. "Starch is a promising material to use, as it is abundant and renewable – it is the second-largest source of biomass on ...
PANI nanofibers can be further fined-tuned by doping and modifying the polymer chain conformation, among other methods, to increase selectivity to certain gases. [ 1 ] [ 2 ] [ 13 ] A typical PANI chemical sensor consists of a substrate, an electrode, and a selective polymer layer. [ 13 ]
