Patent number: 11500044Abstract: A method of enhancing the nuclear spin polarization of target molecules (10) uses a hyperpolarized source material (12) that is co-confined with the target molecules (10) in a porous molecular matrix (20). The matrix (20) may be a D4R-polysiloxane copolymer such as polyoligosiloxysilicone number two (PSS-2) that has recesses of an appropriate diameter. A source material (12), such as parahydrogen, is transferred to the matrix (20) together with the target molecules (10), and an external pressure is applied to force them into the recesses of the matrix (20). The nano-confinement of the source material (12) and target molecules (10) together enables or enhances a transfer of spin polarization from the source material (12) to the target molecules (10). When the target molecules (10) are removed from the matrix (20), the enhanced spin polarization greatly enhances the signal strength of the target molecules (10) in any subsequent magnetic resonance measurement.Type: GrantFiled: February 19, 2019Date of Patent: November 15, 2022Inventors: Eric Breynaert, Johan Martens, Francis Taulelle, Pieter Leo Hendrik Verlooy, Jean-Max Tyburn, James Kempf
