is transforming fields like medicine, electronics, and materials
science, enabling breakthroughs such as targeted drug delivery and faster processors.
Nanotechnology
The prefix “nano” originates from the Greek word “___,” meaning “___,” and in
scientific contexts, it denotes a scale of one-billionth of a meter (10⁻⁹ m).
nanos; dwarf
Materials at the nanoscale, known
as ____, exhibit unique physical, chemical, and biological properties that differ
significantly from their bulk counterparts.
nanomaterials
is a field of science that involves the study of matter at the nanoscale,
with a particular emphasis on the unique, size-dependent properties of solid-state materials
Nanoscience
encompasses a convergence of scientific disciplines, including
solid-state chemistry, synthetic chemistry, molecular biology, solid-state physics, engineering,
and advanced imaging techniques like scanning tunneling microscopy (STM).
Nanoscience
involves
transforming nanoscience concepts into practical applications by observing, measuring,
manipulating, assembling, controlling, and producing materials at the nanometer scale, which
range in size from 1 to 100 nm
Nanotechnology
The term “nanotechnology” was first
coined by ____
Norio Taniguchi
the processing of separation, consolidation, and deformation of materials by one atom or one
molecule
nanotechnology
are often described as “divided matter” due to their minuscule size and
large surface-area-to-volume ratio.
Nanomaterials
Two primary factors differentiate nanomaterials from bulk
materials:
increased surface area and quantum effects
is the application of nanotechnology in biological sciences,
offering new opportunities for research and innovation.
Nanobiotechnology
This combination facilitates the
development of advanced tools and technologies, driving progress in life sciences,
medical research, and applied sciences.
Nanobiotechnology
Intracellular imaging can be achieved by detecting target molecules
using ___ or ___, such as fluorescent
lipids.
quantum dots (QDs) or synthetic chromophores
involves identifying rare cells that differ
physiologically from surrounding cells under normal conditions, such as cancer
cells, lymphocytes, embryonic cells, and HIV-infected T cells.
Sparse cell detection
are microscopic robots, typically measured in nanometers, currently
undergoing research and development.
Nanobots
is the application of nanotechnology in cancer
diagnosis, treatment, and prevention. It involves using nanoparticles, nanocarriers, and
nanosensors to detect cancer at an early stage, deliver drugs directly to tumor cells, and
enhance imaging techniques like MRI and CT scans.
Cancer nanotechnology
– Tracks insulin production continuously,
allowing for immediate assessment of pancreatic cell function.
Real-Time Insulin Monitoring
– Uses electrically conductive carbon
nanotubes to detect insulin levels by measuring electron transfer when
insulin interacts with glucose.
Micro-physiometer Technology
– Synthetic resin glycol beads coated with fluorescent
molecules
Fluorescent Sensors
___focuses on these size-dependent
characteristics, while ___applies them in fields like medicine, biotechnology, and
the food industry.
Nanoscience ; nanotechnology
are special cells that have the remarkable ability to develop into many different
cell types in the body,
Stem cells
____, works at the genetic level, aiming to fix or replace faulty genes responsible for disease.
Gene therapy
is a scientific method where genes are introduced, removed, or changed inside
a person’s cells to treat disease. It helps fix the problem at the source, within the DNA
Gene therapy
key steps in gene therapy (4)
Identify the Faulty Gene ;
Choose the Vector;
