refers to a unit meaning one billionth or ten raised to negative nine (10^-⁹).

Nano

is one billionth of a meter.

Nanometer

refers to the science, engineering and technology conducted at the nanoscale.

Nanotechnology

employs the study and application of exceptional small thing in other areas of science.

Nanoscience and Nanotechnology

Concept of nanoscience and nanotechnology date.

December 29, 1959

Concept of nanoscience and nanotechnology by the physicist:

Richard Feynman

He talks "there's plenty of room at the bottom".

Richard Feynman

Concept of nanoscience and nanotechnology coined by:

Professor Norio Taniguchi

1 nanometer (nm) is equal to a __ of a meter.

Billionth

how to view nano materials.

Electronic Microscope

German engineers ___ and ___ built the first electron microscope during 1930s.

Ernst Ruska, Max Knoll

Type of microscope that utilizes a particle beam of electrons to light up specimen and develop a well magnified image.

Electronic Microscope

produce higher and better resolution than older light microscopes.

Electron Microscope

TWO GENERAL TYPES OF ELECTRONIC MICROSOPE:

Transmission Electron Microscope (TEM), Scanning Electron Microscope (SEM)

It makes use of mechanical probe that gathers information from surface of a material. Developed by ___, and in ___.

Atomic Force Microscope (AFM), Gerd Binig, Calvin Quate, Christoph Gerber, 1986

In ___, ___ and ___ won the Nobel Prize on physics because of this inventions.

Scanning Tunneling Microscope, 1986, Gerd Binig, Heinrich Rohrer

This special type of microscope enables scientist to view and manipulate nanoscale particles, atoms and small molecules.

Scanning Tunneling Microscope

It refers to scaled-up, reliable and cost-effective manufacturing of nanoscale materials, structures, devices and systems.

Nanomanufacturing

it manufactures products by building them up from atomic and molecular scale components.

Bottom-Up Fabrication

it trims down large pieces of materials into nanoscale.

Top-Down Fabrication

it is method in which the tip of an atomic force microscope is "dipped" into a chemical fluid and then utilized to "write" on a surface, like an old- fashioned ink pen onto paper.

Dip Pen Lithography

it depicts an approached wherein a set of components join together to mold an organized structure in the absence of an outside direction.

Self-Assembly

it is a procedure wherein chemicals act in response to form very pure, high-performance films.

Chemical Vapor Deposition

it is a method of generating nanoscale attributes by "stamping" or "printing" them onto a surface.

Nanoimprint Lithography

it is one manner for-depositing extremely controlled thin films.

Molecular Beam Epitaxy

it is a high volume practice for constructing nanoscale devices on a roll of ultrathin plastic or metal.

Roll-To-Roll Processing

it is a means for laying down one-atom-thick layers on a surface.

Atomic Layer Epitaxy

involves operating at a very small dimension and it allows to scientists to make use of the exceptional optical, chemical, physical, mechanical and biological qualities of materials of that small scales.

Nanotechnology

Scale at which much biology occurs.

Bio-Barcode Assay

Scale at which quantum effects dominate properties of materials.

Nanoscale Gold

have far larger surface areas than similar masses of larger-scale materials.

Nanoscale Materials

The best known and most funded program.

US National Nanotechnology Initiative

Two fundamental approaches to manufacturing:

Bottom-Up Fabrication, Top-Down Fabrication

New approaches to the assembly of nanomaterials:

Dip Pen Lithography, Self-Assembly, Chemical Vapor Deposition, Nanoimprint Lithography, Molecular Beam Epitaxy, Roll-To-Roll Processing, Atomic Layer Epitaxy

Distinct Feature of Nanoscale:

Bio-Barcode Assay, Nanoscale Gold, The effect of the increased surface area provided by nanostructured

Government funding for technology in different countries (Dayrit 2005):

European Commission, Japan, Taiwan, India, China, Israel, Australia, Canada, South Korea, Thailand, Malaysia

Possible Applications of Nanotechnology in the Philippines:

ICT and Semiconductors, Food and Agriculture, Environment, Health and Medicine

Benefits and concerns of the application of nanotechnology in different areas:

Environment, Improved detection and removal of contaminants., High reactivity and toxicity., Health, Improved medicine., Ability to cross cell membranes and translocate in the body., Economy, Better products and new jobs, Redistribution of wealth
