摘要:
Disclosed herein are molecule-modified nanoparticles and methods of making and using the same. More specifically, disclosed herein are molecule-modified nanoparticles wherein the molecule is attached to the surface of the nanoparticle via an oligonucleotide. Also disclosed are methods of preparing nanoparticles having oligonucleotides and molecules (e.g., biomolecules, such as proteins, peptides, antibodies, lipids, and/or carbohydrates) attached to the nanoparticle surface, wherein the oligonucleotide and molecule are covalently attached. Further disclosed are methods of detecting an analyte of interest using these disclosed molecule-modified nanoparticles.
摘要:
In one aspect, a method of nanolithography is provided using a driving force to control the movement of a deposition compound from a scanning probe microscope tip to a substrate. Another aspect of the invention provides a tip for use in nanolithography having an internal cavity and an aperture restricting movement of a deposition compound from the tip to the substrate. The rate and extent of movement of the deposition compound through the aperture is controlled by a driving force.

Methods of forming nanoprisms or nanorods from gold seed particles by adding controlled amounts of iodide ion to the growth solution are disclosed.
摘要:
A method that combines on-wire-lithography (OWL) nanogaps, an electric field concentrating technique, and surface enhanced Raman spectroscopy (SERS) is disclosed for sensitive detection of analytes with small sample sizes in a chip format.
摘要:
An improved method of loading tips and other surfaces with patterning compositions or inks for use in deposition. A method of patterning is described, the method comprising: (i) providing at least one array of tips; (ii) providing a plurality of patterning compositions; (iii) ink jet printing at least some of the patterning compositions onto some of the tips; and (iv) depositing at least some of the patterning compositions onto a substrate surface; wherein the ink jet printing is adapted to prevent substantial cross-contamination of the patterning composition on the tips. Good printing reproducibility and control of printing rate can be achieved. The surfaces subjected to ink jet printing can be treated to encourage localization of the ink at the tip. The method is particularly important for high density arrays.
