Abstract: Compositions and methods to 3D print high quality inorganic nanostructures from a nanocomposite ink using two-photon polymerization are provided. Methods provide capability for 3D printing inorganic silica structures with sub-200 nm resolution with controlled crystallinity and doping. The final 3D printed inorganic product is shown to be pure SiO2, which can be in either glass or crystalline polymorph depending on the sintering process. The 3D printed fabricated products also show remarkable optical performance with the 3D printed micro-toroid optical resonators having quality factors (Q) over 104. For optical applications, doping and co-doping of rare earth salts such as Er3+, Tm3+, Yb3+, Eu3+ and Nd3+ can be directly implemented in the printed SiO2 structures.

Abstract: A method for minimally invasive deep brain simulation (DBS) involves obtaining a target location for the DBS, obtaining an anatomical model, and simulatively determining, for a set of antennas endocranially implanted at first positions and emitting electromagnetic waves differing by a frequency offset, a first envelope signal at the target location, using the anatomical model. The first envelope signal resulting from interference of the electromagnetic waves at the target location has an envelope signal frequency corresponding to the frequency offset.

Abstract: Embodiments of the present disclosure pertain to methods of opening a lipid bilayer by associating the lipid bilayer with a molecule that includes a moving component capable of moving (e.g., rotating) in response to an external stimulus; and exposing the molecule to an external stimulus before, during or after associating the molecule with the lipid bilayer. The exposing causes the moving component of the molecule to move and thereby open the lipid bilayer (e.g., by pore formation). The external stimuli may include an energy source, such as ultraviolet light. The opened lipid bilayer may be a component of cell membranes in vitro or in vivo. The opening of the lipid bilayer may allow for the passage of various materials (e.g., active agents, such as peptide-based drugs) through the lipid bilayer and into cells. Additional embodiments of the present disclosure pertain to the aforementioned molecules for opening lipid bilayers.

Abstract: Some embodiments are directed to methods for serially expanding an artificial heart valve within a pediatric patient. For example, the artificial heart valve can be implanted into the pediatric patient during a first procedure, and then expanded during a second procedure to accommodate for the pediatric patient’s growth. Some embodiments include introducing an expander into the implanted valve when the frame is expanded to a first working diameter, and then actuating the expander to expand the frame to a second working diameter greater than the first working diameter, to accommodate for the pediatric patient’s growth.

Abstract: Provided herein are hybrid capture-based methods to extract single-stranded DNA or RNA directly from non-treated biospecimens. The methods allow for the detection and analysis of unexplored short single-stranded DNA (sssDNA, mean length 50 nt) and ultrashort single-stranded DNA (ussDNA, mean length 15 nt) of human origin present in the biospecimen. The methods allow the discovery of unexplored short single-stranded DNA (sssDNA) in isolated red blood cells, which were believed to be deprived of nucleic acids because of the lack of a nucleus in mature red blood cells. The DNA or RNA extracted using the disclosed methods can be used as disease prognostic biomarkers and treatment predictive biomarkers.
