A facile room-temperature method for assembling colloidal copper sulfide (CuS) nanoparticles into highly electrically conducting calcogenide material layer films utilizes ammonium sulfide for connecting the nanoparticles, while simultaneously effecting templating surfactant ligand removal. The foregoing process steps transform an as-deposited insulating films into a highly conducting films (i.e., having a conductivity at least about 75 S·cm). The methodology is anticipated as applicable to copper chalcogenides other than copper sulfide, as well as metal chalcogenides other than copper chalcogenides.

Fabrication of hierarchical silica nanomembranes and uses thereof for solid phase extraction of nucleic acids

Номер: US20170096660A1
Автор: Tza-Huei Wang, Yi Zhang
Принадлежит: JOHNS HOPKINS UNIVERSITY

The present invention provides a novel method to fabricate silica nanostructures on thin polymer films based on silica deposition and self-wrinkling induced by thermal shrinkage. These micro- and nano-scale structures have vastly enlarged the specific area of silica, thus the silica nanomembranes can be used for solid phase extraction of nucleic acids. The inventive silica nanomembranes are suitable for nucleic acid purification and isolation and demonstrated better performance than commercial particles in terms of DNA recovery yield and integrity. In addition, the silica nanomembranes have extremely high nucleic acid capacity due to its significantly enlarged specific surface area of silica. Methods of use and devices comprising the silica nanomembranes are also provided.
