Abstract
A novel, advanced polymeric swab is disclosed herein. The swabs have a surface texture that allows for independent motion between microscale regions, are reusable with no loss of accuracy or efficiency, and are fabricated from optoelectronically-active elements to minimize static charging during repeated use.
Claims13
A polymeric swab comprising:
- a substrate, wherein the substrate comprises a first surface, wherein the first surface comprises copper or gold;
- and
- a plurality of microfabricated fibers over the first surface, wherein the plurality of microfabricated fibers is configured to contain a surface texture that allows for independent motion between microscale regions, wherein a spacing between each microfabricated fibers of the plurality of microfabricated fibers ranges from 10 nm to 100 nm, wherein each microfabricated fiber of the plurality of microfabricated fibers comprises a polymer, wherein the polymer is configured to not outgas at ion-mobility spectrometry conditions.
A swab comprising:
- a substrate, wherein the substrate comprises a first surface, wherein the first surface comprises copper or gold;
- and
- a plurality of microfabricated fibers over the first surface, wherein a spacing between each microfabricated fibers of the plurality of microfabricated fibers ranges from 10 microns to 200 microns, wherein the each microfabricated fibers of the plurality of microfabricated fibers comprises polythiopene.
