Organic Materials and Nanotechnology
Introduction
Organic materials are materials composed of carbon-containing compounds. They are found in nature in a wide variety of forms, including plants, animals, and minerals. Organic materials have been used for centuries for a variety of purposes, including food, clothing, and shelter. In recent years, there has been growing interest in the use of organic materials in nanotechnology.
Basic Concepts
Nanotechnology is the science of manipulating matter at the nanoscale, which is typically defined as being between 1 and 100 nanometers (nm). One nanometer is one billionth of a meter. At this scale, materials can exhibit unique properties that are not seen at larger scales. For example, organic materials at the nanoscale can be stronger, lighter, and more conductive than their larger-scale counterparts.

Organic Materials and Nanotechnology Experiment
Background
Organic materials are molecules containing carbon atoms that form the basis of all living things. Nanotechnology is the study of materials at the atomic and molecular level. By manipulating organic materials at this scale, scientists can create new materials with unique properties that can be used in a variety of applications.
Experiment
Materials
- Graphene oxide (GO) powder
- Water
- Sodium hydroxide (NaOH)
- Hydrochloric acid (HCl)
- Stirring rod
- Beaker
- Spectrophotometer
Procedure
- Suspend 10 mg of GO powder in 100 mL of water.
- Add 10 mL of 1 M NaOH solution to the GO suspension and stir for 30 minutes.
- Add 10 mL of 1 M HCl solution to the GO suspension and stir for 30 minutes.
- Measure the absorbance of the GO suspension at 600 nm using a spectrophotometer.
Results
The absorbance of the GO suspension will decrease after the addition of NaOH and then increase after the addition of HCl. This indicates that the GO sheets have been exfoliated and dispersed in the water.
Significance
This experiment demonstrates the use of organic materials in nanotechnology. By exfoliating and dispersing GO sheets, scientists can create new materials with unique properties that can be used in a variety of applications, such as sensors, solar cells, and batteries.
