Title: Fahimeh Zarrin: Innovator in Electrospray Technology
Introduction
Fahimeh Zarrin is a prominent inventor based in Saint Paul, MN (US). She has made significant contributions to the field of electrospray technology, holding 2 patents that showcase her innovative approach to producing uniform submicrometer droplets and determining the concentration of macromolecules.
Latest Patents
One of her latest patents is an "Electrospray apparatus for producing uniform submicrometer droplets." This invention involves a nebulizer that generates an aerosol comprised of submicrometer droplets that are substantially uniform in size. A liquid sample is supplied at a controlled rate to a capillary needle of the nebulizer, where droplets are formed due to an electrical field. The invention also incorporates sources of ionizing radiation to counteract the disintegration of droplets caused by Coulomb forces. Additionally, a controlled air sheath is introduced to transport droplets more rapidly downstream, enhancing the efficiency of the nebulizer.
Another notable patent is the "Method and apparatus for determining concentration of macromolecules and colloids." This apparatus utilizes an electrospray mechanism to form droplets from a liquid sample. The droplets are dried to form an aerosol, which is then analyzed by a condensation nucleus counter to count the target macromolecules and colloids. This innovative method is capable of detecting very small macromolecules, including individual molecules with a molecular weight as low as 10,000.
