Improved metal complex chemical precursors for atomic layer deposition (ALD) and chemical vapor depostion (CVD) using bicyclic guanidines

A new class of metal complex precursors has been identified for use in atomic layer deposition (ALD) and chemical vapor deposition (CVD), using bicycle guanidines as ligands as opposed to acetamidines. The ALD process involves the alternating…

Vertical silicon nanowires as a universal platform for highly efficient delivery of bioactive molecules into living cells

This platform consists of an array of surface-modified vertical silicon nanowires that have been chemically grown or etched on a wafer and to which virtually any kind of bioactive species (drug, protein, nucleic acid, nanoparticles) may be attached…

Cyborg tissue: Macroporous nanowire nanoelectronic scaffolds for synthetic tissues

This technology uses macroporous, flexible and free-standing nanowire nanoelectronic scaffolds (nanoES), and their hybrids with synthetic or natural biomaterials. 3D macroporous nanoES mimic the structure of natural tissue scaffolds. The structures…

Invention

Paper-supported 3D cell culture for cell and tissue-based bioassays

In this new approach, cells are cultured in 3D on a paper scaffold by adding a hydrogel precursor, as a fluid containing suspended cells, to a paper support, allowing the cell-containing fluid to distribute through the paper by capillary wicking,…
