3. INTRODUCTION:
Nanotechnology
❖ A nanometer is one-billionth of a meter.
❖ Nanotechnology is the DESIGN, FABRICATION and UTILIZATION of MATERIALS, STRUCTURES and
DEVICES which are less than 100 nm.
Why Nanotechnology?
❖ ULTRASMALL (miniaturized) sensors, communication and navigation systems with very LOW MASS,
VOLUME and POWER CONSUMPTION are NEEDED.

4. MINIATURIZED DEVICES:
❖ Miniaturized devices are small-scale electronic or mechanical systems that have been designed
and manufactured to be significantly smaller.
❖ They have applications in various fields, including electronics, medicine, and engineering.
Examples: microchips, microsensors.
❖ Nanotechnology plays a crucial role in the development and functioning of miniaturized
devices.

6. Here are some ways nanotechnology is involved in miniaturized devices:
1. Nano-scale Manufacturing: Nanotechnology enables the fabrication of tiny components with extraordinary
precision, allowing for the assembly of miniaturized devices with high levels of integration and performance.
2. Improved Materials: Nanomaterials, such as carbon nanotubes and nanoparticles, can be used to create
stronger, lighter and more conductive materials, which are essential for miniaturized devices.
3.Energy Efficiency: Nanotechnology can help reduce power consumption in miniaturized electronic devices,
extending battery life and making them more efficient.
4. Biomedical Applications: Nanotechnology has enabled the development of miniaturized medical devices
for drug delivery, diagnostics, and imaging at the cellular and molecular levels.

8. Examples of Biomedical Devices:
1. Nanoparticles for Drug Delivery:
❖ Made of biocompatible materials like lipids or polymers, can carry drugs to specific cells or tissues.
Ex - liposomal doxorubicin is used to treat cancer.
2. Nanobiosensors:
❖ Nanoscale biosensors can detect specific biomolecules or pathogens.
Ex - carbon nanotubes with antibodies can be used to detect proteins associated with diseases
3. Nanorobots for Targeted Therapy:
❖ Nanorobots, controlled remotely or autonomously, can navigate through the body to deliver drugs
or perform specific tasks, such as removing clots or cancer cells.
4. Nanoparticles for Gene Therapy:
❖ Nanotechnology is used to deliver genetic material to correct or replace faulty genes. Lipid
nanoparticles and viral vectors at the nanoscale are employed in gene therapy applications.

9. NANOTUBES-MARKING MUTATIONS:
❖ A nanodevice that will help identify DNA changes associated with cancer is the nanotube.
❖ Nanotubes are carbon rods about half the diameter of a molecule of DNA that not only can detect the
presence of altered genes, but they may help to pinpoint the exact location of those changes.
❖ To prepare DNA for nanotube analysis, scientists must attach a bulky molecule to regions of the DNA
that are associated with cancer.
❖ They can design tags that seek out specific mutations in the DNA and bind to them.
❖ Once the mutation has been tagged, researchers use a nanotube tip resembling the needle on a record
player to trace the physical shape of DNA and pinpoint the mutated regions.
❖ Nanotube creates a map showing the shape of the DNA molecule, including the tags identifying
important mutations.
❖ Since the location of mutations can influence the effects they have on a cell, these techniques will be
important in predicting disease.

12. MICROFLUIDICS (LAB ON A CHIP):
❖ The newest technologies within nanodiagnostics involve microfluidic or "lab on a chip" systems,
in which the DNA sample is completely unknown.
❖ The idea behind this kind of chip is simple: the combination of numerous processes of DNA
analysis are combined on a single chip composed of a single glass and silicon substrate.
❖ The device itself is composed of microfabricated fluidic channels, heaters, temperature sensors,
electrophoretic chambers, and fluorescence detectors to analyze nanoliter-size DNA samples.
❖ This device is described as capable of measuring aqueous reagent and DNA-containing solutions,
mixing the solutions together, amplifying or digesting the DNA to form discrete products, and
then separating and detecting those products.
❖ Using a pipette, a sample of DNA containing solution is placed on one fluid-entry port and a
reagent containing solution on the other port. Capillary action draws both solutions into the
device.
