Abstract
This disclosure relates to systems and methods for 3D printed eutectic extraction sorbents. The application discloses the use of both SLA and LCD printers as well as modifications to those printers to make them suitable for inclusion in the systems and methods disclosed herein. Also described are methods of manufacturing eutectic extraction sorbents and methods of analyte extraction using the eutectic extraction sorbents.
Claims20
A system for 3D printing eutectic extraction sorbents comprising:
- a photocuring 3D printer utilizing a build plate having a plurality of holes and a resin tank formed of a plurality of individual wells with a mixture of a hydrogen bond donor, a hydrogen bond acceptor, and a photoinitiator, the mixture placed in the plurality of wells to form a plurality of 3D printed eutectic extraction sorbents on the build plate;
- a fabrication device that prepares the 3D printed eutectic extraction sorbents for extraction;
- at least one container for conditioning, extraction, and desorption of the 3D printed eutectic extraction sorbents.
A eutectic extraction sorbent comprising:
- a eutectic material comprised of a hydrogen bond donor and a hydrogen bond acceptor,
- wherein the eutectic extraction sorbent is in the form of a blade or a fiber;
- wherein the hydrogen bond donor comprises N-(hydroxymethyl) acrylamide, N-isopropylacrylamide, N-vinylcaprolactam, maleic acid, acrylic acid, methacrylic acid, acrylamide, itaconic acid, 4-acryloylmorpholine, malonic acid, N,N′-methylenebis(acrylamide), hydroxyethyl methacrylate, citric acid, amidoxime, tannic acid, oxalic acid, benzeneimidamide, trifluorobenzeneimidamide, propanimidamide, diaminopyridine, piperazinediamine, diaminopropane, ethylene glycol, triethylene glycol, succinic acid, sulfonic acid, levulinic acid, formic acid, phosphoric acid, 1,4-butanediol, and 2,3-butanediol, or a combination or mixture of the foregoing;
- and
- wherein the hydrogen bond acceptor comprises choline chloride, vinyl acetate, urea, ethylammonium chloride, acetylcholine chloride, tetrabutylphosphonium chloride, tetrabutylammonium chloride, cholinium bromide methacrylate, diallyldimethylammonium chloride (DMDAAC), and methyl methacrylate, alanine, betaine, glycine, guanidine hydrochloride, tetramethyl ammonium chloride, tetraethyl ammonium chloride, tetrapropyl ammonium chloride, methyl triethyl ammonium chloride, butyl trimethyl ammonium chloride, chlorocholine chloride, allyl trimethyl ammonium chloride, benzyl trimethyl ammonium chloride, benzyl triethyl ammonium chloride, or a mixture thereof.
