Materials show different functions or properties when their sizes are made in the nanometer scale.
|
|
|
|
|
Molecular systems that regulate and sustain normal cellular functions are at the ten-nanometer scale, and therefore interact (are affected by) strongly with nanoparticles of that size.
|
|
|
|
|
Nanometer scale particles can be created in solution, starting with their atomic ion forms, by controlled oxidation and reduction reactions.

|
|
Biology: Cells, and intracellular organelles such as mitochondria, are enclosed by semipermeable membranes that regulate their interactions with their surroundings.
|
|
|
|
|
Biology: The function of mitochondria in cellular energy production and its role in converting glucose to carbon dioxide
|
|
|
|
|
Chemistry: Chemical reaction rates depend on factors such as concentration, temperature and pressure.
|
|
|
|
|
Chemistry: The temperature, pressure, volume, and number of molecules of a gas system is related through the ideal gas law: PV = nRT
|
|
|
|
|
Physiology: Difference in bacteria, virus and fungi, and effective treatments of these infections.
|
|
|
|
|
Physics: Light has wave properties, identifiable by a characteristic wavelength that determines its interaction with objects of certain size (e.g, the yellowish tint of the Ag nanoparticle solution and its progressive shift towards brownish-green as the nanoparticles aggregate into larger sizes)

Scientific Investigation and Experimentation: Select and use appropriate tools and technology to perform tests, collect data, analyze relationships and display data.
|
|
|
|
|
Scientific Investigation and Experimentation: Identify possible reasons for inconsistent results, such as sources of error or uncontrolled conditions.
