9th–17th centuries.- Brilliant ceramic enamels and brilliant “luster” used Ag, Cu, and other nanoparticles.

13th-18th centuries.-  Production of saber blades, cementite nanowires and carbon nanotubes were used to provide strength and strength.

16th.- Italians used nanoparticles in the creation of Renaissance ceramics.

1857.- Michael Faraday studied the preparation and properties of colloidal suspensions of “ruby” gold. Faraday demonstrated how gold nanoparticles produce solutions of different colors under certain lighting conditions.

1959.- The American physicist and Nobel Prize laureate Richard Feynman introduced the concept of nanotechnology 

1974.- Norio Taniguchi was the first to use and define the term “nanotechnology” as: “nanotechnology mainly consists of the processing of separation, consolidation, and deformation of materials by one atom or one molecule”

2 approaches are developed that describe the different possibilities for the synthesis of nanostructures. These manufacturing approaches fall into different categories: Top-down and bottom-up (grades of quality, speed, and cost)

1981.- Gerd Binnig and Heinrich Rohrer invented a microscope at the IBM Zurich Research Laboratory, the STM.

1982.- The conceptual foundation for DNA nanotechnology was first laid out by Nadrian Seeman

1983.- The group published the first STM image of the reconstructed Si(111)-7 x 7 surface.

1990.- Don Eigler of IBM at Almaden STM to manipulate 35 individual xenon atoms on a nickel surface and formed the IBM logo letters. (STM was invented to expose surfaces on the atomic scale)

In 1990.- Scientists analyzed the cup using a TEM to explain the phenomenon of dichroism. The Lycurgus cup is recognized as one of the oldest synthetic nano materials.

1991.- Iijima et al. observed hollow graphitic tubes or carbon nanotubes by TEM that form another member of the fullerene family.

2000.- President  Clinton advocated for the funding of research in the field of nanotechnology.

2003.- President Bush signed into law the Nanotechnology Research and Development Act of the 21st Century.

2004.- A new class of carbon nanomaterials called carbon dots was discovered. (After the discovery of “graphene” carbon-based materials became the backbone of almost every field of science and engineering.)

 2006.-Paul Rothemund developed the “scaffolded DNA origami“

2- Frontiers in Nanotechnology -"Plasmonic Nanostructures for Optically Induced Movement"

The main idea of the article is the following one: “The interaction of a light beam with a microscopic object can generate forces and torques, allowing manipulation even if the source of forces is at a considerable distance from the point of application”. It is then described the different effects nanotechnology could have with different properties. For example The momentum density.

Due to the high expression of the CD44 receptor on the surface of tumor cells, we encapsulated the chondroitin sulfate gel shell (CS-shell) with an apoptosis-promoting and CD44-targeting effect on the surface of DOX@MOF-COD nanoparticles. Which can accurately and efficiently deliver drugs to the tumor site and enhance the effect of reversing drug resistance

This is because they can improve different objects in different ways. The additives are anything new added to an original recipe. For example, vitamins, antioxidants, and preservatives. This could enhance the food's flavor, how easily they are absorbed into the body, or its nutritional values.
