What are Good Laboratory Practices (GLP)?

Good Laboratory Practices (GLP) are a set of rules and procedures followed in laboratories to ensure safety, accuracy, reliability, and quality of laboratory work.

Principles of Good Laboratory Practices

1. Maintain Cleanliness

  • Keep the laboratory clean and organized.
  • Clean work benches before and after experiments.

2. Follow Safety Rules

  • Wear a lab coat, gloves, and safety goggles when required.
  • Follow all laboratory instructions carefully.

3. Proper Handling of Chemicals and Specimens

  • Read labels before using chemicals.
  • Handle biological samples carefully to avoid contamination.

4. Accurate Record Keeping

  • Record observations and results clearly.
  • Label all samples, reagents, and equipment properly.

5. Use Equipment Correctly

  • Operate laboratory instruments according to instructions.
  • Ensure equipment is clean and in good working condition.

6. Prevent Contamination

  • Use sterile materials when necessary.
  • Do not touch samples with bare hands.

7. Proper Waste Disposal

  • Dispose of chemical, biological, and sharp wastes in designated containers.
  • Follow laboratory waste management guidelines.

8. Personal Hygiene

  • Wash hands before and after laboratory work.
  • Do not eat, drink, or smoke in the laboratory.

Importance of GLP

  • Ensures accurate and reliable results.
  • Protects laboratory personnel from hazards.
  • Prevents contamination and errors.
  • Improves the quality of scientific work.
  • Maintains a safe working environment.

Precautions

  • Never perform unauthorized experiments.
  • Report accidents immediately.
  • Keep emergency equipment accessible.
  • Follow the supervisor's instructions at all times.

Techniques to Construct Nanostructures and Characterisation of Nanoparticles 1. Techniques to Construct Nanostructures Nanostructures are materials with size in the nanometer range (1–100 nm). Special techniques are used to create and study them. A. Scanning Probe Instruments Scanning probe instruments are used to image, measure, and manipulate materials at the nanoscale . They work by scanning a very sharp tip over the surface. 1. Scanning Tunneling Microscope (STM) Uses a sharp metal tip and a conducting sample When the tip comes very close to the surface, electrons “tunnel” between tip and sample The tunneling current changes with surface atoms Produces atomic-level images Uses: Study surface atoms of metals and semiconductors Construct nanostructures atom by atom Limitations: Works only with conductive materials 2. Atomic Force Microscope (AFM) Uses a very fine tip attached to a flex...

Nanoparticle Synthesis Using Plants, Bacteria, Fungi, and Viruses 1. Green Synthesis of Nanoparticles Green synthesis means producing nanoparticles using natural biological materials instead of chemicals. It is eco-friendly, low-cost, and safe. Biological organisms contain proteins, enzymes, metabolites, or biomolecules that can reduce metal ions into nanoparticles. 2. Plant-Mediated Nanoparticle Synthesis Plants contain phytochemicals like flavonoids, alkaloids, terpenoids, phenolics, sugars, and proteins. These act as reducing and stabilizing agents. Process • Prepare plant extract (leaf, stem, bark, fruit). • Mix extract with metal salt solution (e.g., AgNO₃ for silver). • Phytochemicals convert metal ions into nanoparticles. • Colour change confirms formation (e.g., silver turns brown/yellowish). Advantages • Very simple process • No need for microbes • Fast reaction Examples • Silver nanoparticles from neem, tulsi, aloe vera • Gold nanoparticles from tea extract or...
