Recent developments in nanofiber-based sensors for disease detection, immunosensing, and monitoring 2023-05-05

In recent years, healthcare and treatments have trended towards an individualized approach—being able to assess and meet the needs of specific individuals. As healthcare focuses on improving the wellbeing of individual patients, arises the need for the development of sensors that are capable of detecting specific biomarkers or chemical markers indicative of a user's health [1], [2], [3]. Such monitoring informs healthcare and treatment-related decisions and is capable of detecting diseases in earlier stages. Enhanced and earlier detection of illnesses, including malaria [4], [5], [6], various cancers [7], [8], [9], among many others, improves patient outcomes by facilitating treatment during earlier stages—a key for remediating any ailment. A recent development, however, has been the inclusion of nanofibers for these sensing methods.

The filtration application of nanofibers 2023-04-26

Elecotrospun nanofibers,with fiber diameters of 0.25 microns have been used in industrial, consumer anddefense filtration applications for more than twenty years. Electrospunnanofibers have fiber diameters that are 5-10 times smaller than the smallestmeltblown fibers available. Recently, Ultra-Web nanofiber filter media hasbecome available to the non-wovens and filtration industries for a broad rangeof filtration applications.

Visualized concentration sensors based on fluorescence indication in a dye-doped polymer microwire 2023-04-25

We demonstrate visualized microwire sensors based on fluorescence indication for detecting the concentrations of the aqueous solutions. The single Rhodamine (RhB) doped polymer microwires (PMWs) which are excited by the waveguiding excitation method are used as the sensory area. According to the fluorescent microimages of the PMWs, stable periodic oscillations could be observed in the RhB-doped PMWs. The fluorescent period which is dependent on the concentration is further analyzed by image processing and information extraction algorithms. Corresponding to a 1.0% change, the period length change of the visualized sensor reaches ∼380 nm, ∼270 nm, and ∼300 nm in NaCl, KCl, and sucrose solutions, respectively. The dection limits of the three solutions are estimated to be around 1.5 × 10−4%. The dye-doped PMW sensors by fluorescence indication and image analysis proposed here realize the direct visualized detection in concentration sensing, making it possible to avoid the challenges of sta

Electrospinning to Produce Polymer Based Nanofibers 2023-04-17

Polymer-based nanofibers are produced using a process called electrospinning. In this process, the polymer material (sometimes a polymer melt) is electrically charged and then subjected to an applied electrical field where the polymeric material is removed and 'whipped' from the source in fine 'needle-like' structures to form nanofibers.
