Abstract: The present disclosure discloses a through-silicon-via structure and a method for preparing the same, a through-silicon-via interconnection structure and a method for preparing the same, and an electronic device, and belongs to the technical of semiconductors. The method includes forming an initial through hole running through a silicon-based substrate, forming a silicon oxide film on an inner wall of the initial through hole through oxidization, and removing the silicon oxide film to obtain a through-silicon-via structure with a through-silicon-via. The inner wall of the initial through hole will gradually tend to be smooth after being oxidized to form the silicon oxide film with a certain thickness, so that the inner wall of the through-silicon-via of the through-silicon-via structure formed after the silicon oxide film is removed is relatively smooth, which will not affect the quality of the conducting material subsequently grown on the inner wall of the through-silicon-via.

Abstract: The present invention provides for lipid:nucleic acid complexes that have increased shelf life and high transfection activity in vivo following intravenous injection, and methods of preparing such complexes. The methods generally involve contacting a nucleic acid with an organic polycation to produce a condensed nucleic acid, and then combining the condensed nucleic acid with a lipid comprising an amphiphilic cationic lipid to produce the lipid:nucleic acid complex. This complex can be further stabilized by the addition of a hydrophilic polymer attached to hydrophobic side chains. The complex can also be made specific for specific cells, by incorporating a targeting moiety such as an Fab? fragment attached to a hydrophilic polymer.

Abstract: The present invention provides for liposomes loaded with a therapeutic agent, which liposomes are targeted to a cell of interest by incubation with a targeting protein protein conjugated to a linker molecule comprising a hydrophobic domain, a hydrophilic polymer chain terminally attached to the hydrophobic domain, and a chemical group reactive to one or more functional groups on a protein molecule and attached to the hydrophilic polymer chain at a terminus contralateral to the hydrophobic domain, for a time sufficient to permit the hydrophobic domain to become stably associated with the liposome.

Abstract: The invention provides methods of attaching proteins to lipidic microparticles with efficiencies of at least 77%. The proteins are attached to linker molecules comprising a hydrophilic domain and a hydrophobic domain. The proteins can be antibodies, antibody fragments, hormones, growth factors, enzymes, or nucleic acid binding proteins, or other proteins. The proteins can be chemically conjugated to the linker molecules, or they can be fused to the linker molecules by recombinant techniques.
