Patent number: 7690325Abstract: Some embodiments of the present invention provide an apparatus and method in which material is deposited upon a surface from an elongated beam having an aperture defined therein through which the material is moved by passive adsorption. The elongated beam can be substantially planar along substantially its entire length, can be oriented at an acute angle with respect to the surface during deposition processes, and can have a length no greater than about 2 mm. In some embodiments, the aperture can be elongated, can extend from a material reservoir to a location short of the terminal end of the elongated beam or through the terminal end of the elongated beam, and can have a portion extending through the thickness of the elongated beam.Type: GrantFiled: April 29, 2005Date of Patent: April 6, 2010Assignee: Bioforce Nanosciences, Inc.Inventors: Eric R. Henderson, Juntao Xu, Michael P. Lynch, Curtis L. Mosher, Janice Lillian Huff, Saju Rappai Nettikadan

Patent number: 7060448Abstract: The present invention is a method for selectively removing objects from a surface utilizing a probe. The probe is scanned over the surface utilizing a greater and greater relative amount of force so that a certain number of the objects are removed from the surface. The force required to remove the objects from the surface can be calculated utilizing Hook's law and the spring constant of the probe. After removal of the objects that have a relatively weaker binding affinity with the surface, the remaining objects can be harvested, characterized, and subjected to further study.Type: GrantFiled: October 4, 2004Date of Patent: June 13, 2006Assignee: BioForce Nanosciences, Inc.Inventors: Eric Henderson, Curtis Mosher

Patent number: 7008769Abstract: The present invention is a dedicated apparatus for the formation of array that includes one or more deposition domains comprised of one or more deposition materials. The present invention may include an X, Y controller, an X, Y translation stage, a loading substrate, a deposition substrate, a Z controller, and a deposition probe. A computer controls all of the relative positions of each of the components. Furthermore, the present invention utilizes a humidity control system to create a capillary bridge between the probe and the substrate for transferring the deposition material between the loading substrate, the deposition probe, and the deposition substrate.Type: GrantFiled: August 14, 2001Date of Patent: March 7, 2006Assignee: BioForce Nanosciences, Inc.Inventors: Eric Henderson, Curtis Mosher

Patent number: 6998228Abstract: The invention is a method for the formation and analysis of novel miniature deposition domains. These deposition domains are placed on a surface to form a molecular array. The molecular array is scanned with an AFM to analyze molecular recognition events and the effect of introduced agents on defined molecular interactions. This approach can be carried out in a high throughput format, allowing rapid screening of thousands of molecular species in a solid state array. The procedures described here have the added benefit of allowing the measurement of changes in molecular binding events resulting from changes in the analysis environment or introduction of additional effector molecules to the assay system. The processes described herein are extremely useful in the search for compounds such as new drugs for treatment of undesirable physiological conditions.Type: GrantFiled: June 25, 2002Date of Patent: February 14, 2006Assignee: Bioforce Nanosciences, Inc.Inventors: Eric Henderson, Curtis Mosher, Michael P.

Patent number: 6897015Abstract: The present invention includes a method and apparatus for the detection of a target material. The method and apparatus includes providing a substrate with a surface and forming a domains of deposited materials thereon. The deposited material can be placed on the surface and bound directly and non-specifically to the surface, or it may be specifically or non-specifically bound to the surface. The deposited material has an affinity for a specific target material. The domains thus created are termed affinity domains or deposition domains. Multiple affinity domains of deposited materials can be deposited on a single surface, creating a plurality of specific binding affinity domains for a plurality of target materials. Target materials may include, for example, pathogens or pathogenic markers such as viruses, bacteria, bacterial spores, parasites, prions, fungi, mold or pollen spores.Type: GrantFiled: May 30, 2002Date of Patent: May 24, 2005Assignee: BioForce Nanosciences, Inc.Inventors: Eric R.

Patent number: 6716578Abstract: The invention is a solid state process for analyzing genomes by visualizing sequence specific markers (e.g., proteins that bind a defined DNA sequence elements) by scanning probe microscopy. The method includes linear display of the nucleic acid on a solid surface, image acquisition by the scanning probe microscope, and digital data analysis. The acts of the method result in a bar code type display of each fragment of the DNA sample. These bar codes are then used to place the fragments in the order they appear on the original DNA sample.Type: GrantFiled: March 7, 2000Date of Patent: April 6, 2004Assignee: BioForce Nanosciences, Inc.Inventors: Eric Henderson, Michael P.
