摘要:
A functionalized specimen support for use in charged particle microscopy is provided that includes a specimen support surface configured to support specimens (e.g. DNA strands 1051) during an interrogation of the specimens with a charged particle microscope, the specimen support surface having functionalized sites 1031, each functionalized site configured to maintain position of a portion of one of the specimens at the functionalized site by way of attachment, attraction, or a combination thereof.

The present invention is directed to nanoscale fabrication of nano-materials with application in electronics, energy conversion, bio-sensing and others. Specifically, the invention is directed to arbitrary, that is periodic and non-periodic, assembly of nano-objects on I D and 2D arrays. The present invention utilizes self-organization properties of nanoscale bio-encoded building blocks, programmability of biomolecular interactions, and simple processing techniques for providing arbitrary by-design fabrication capability. Specifically, the present invention utilizes double stranded DNA attached to a surface and intercalating PNA-DNA hybrids attached to nano-objects to bind the nano-objects to the dsDNA in a site specific manner. The present invention allows for an integration of a large number of nano-components in unified well-defined systems. Accordingly, the present invention is applicable for fabrication of I D and 2D structures of various by-design placements of nano-objects of multiple types, including metal, semiconducting and organic nano-objects.
摘要:
The present invention relates to a label-free biosensor system, a method for manufacturing said label-free biosensor system, its use for detecting biochemical reactions and/or bindings, enzymatic reactions, nucleic acid hybridizations, protein-protein interactions and protein-ligand interactions, as well as an assay method for detecting and/or quantifying an analyte of interest in a biological sample which comprises detecting the Recognition Induced Birefringence (RIB) generated in the presence as opposed to the absence of said analyte by bringing said sample into contact with said label-free biosensor system.

The present disclosure provides systems, kits, devices and methods for indirect transfer of multiple sets of nucleic-acid and other molecules to cells as exemplified by indirect transfection of sets of nucleic-acid molecules to viable cells.
摘要:
The present invention describes a method for identification of areas of a sample from which nucleic acid molecules originate using labeling of said nucleic acid molecules by two-dimensionally distributed oligonucleotide markers. Further analysis of hybrids between the nucleic acid molecules and the oligonucleotide markers allow identification of the original position of the labelled nucleic acid molecules in the sample.

摘要:
The present invention provides methods for replication of nucleic acid molecules distributed on a surface or within a layer by transferring them to a target surface covered with oligonucleotides, and fixation of transferred molecules by hybridization to complementary sequences.
摘要:
The present invention relates to a method for screening a sol composition for sol-gel biochips, which is used to immobilize a probe on a surface-untreated substrate, also relates to a sol composition screened by said method and a sol-gel biochip comprising said sol composition immobilized thereon. The sol composition screened by the disclosed method can be mixed with a probe, and the sol mixture can be integrated on 96-well plates, which are widely used in existing bioassays, without surface treatment. Also, the biochip can provide a sensitive and specific good analysis results because this immobilization methods of probe maintain the nature of probes without modification.
