M8 Flashcards
A branch of technology that deals with the manipulation and
study of matter at the nanoscale.
nanotechnology
It covers all types of
research and technologies that deal with the special
properties of matter on an atomic molecular and
supramolecular scale.
nanotechnology
means a billionth of a meter
nano
are composed of multilayered
nano-scale structures. These structures
create brilliant colors and also help the
butterfly shed water and dirt.
scales on the surface of a butterfly’s
wing
are some of the toughest
materials known to man. The silks get
their strength from thin crystalline proteins
only nanometers wide.
Spider silks
the basic switches that enable all modern computing, have gotten smaller and smaller through nanotech
transistors
a one nanometer transistor was first introduced in
2016
are used to create displays that have better color, low energy consumption and longer service life
nanomaterials
the protein that carries oxyget through the body is 5.5 nanometers in diameter
hemoglobin
one of the building blocks of human life, is only about 2.5 nanometers in diameter
a strand of DNA
can enhance durability and reduce the chance of rejection by the bodu
nano coatings on artificial joints and other medical implants
is at the forefront of some of the newest, most sophisticated tools used for detecting and treating cancer
nanotech
enables the development of next generation materials that are stronger, lighter and more durable
nanotech
has allowed us to develop paints and coatings that are self-cleaning, have greater durability and break down pollutants in the air
nanotech
use nanotech to regulate UV light penetration and increase energy efficiency
“smart” windows

solutions that help to create more drinkable water
refer broadly to
organisms that are produced when selected individual genes
are transferred from a given donor organism into another
target organism, typically conferring desired properties to the
new organism.
Genetically modified organisms (GMOs)
can include plants, animals, and enzymes.
Genetically modified organisms (GMOs)
what are some things GMOs are modified to do
Pest Resistance
Virus Resistance
Herbicide Tolerance
Fortification
Cosmetic Preservation
has been modified to include a gene from
the soil bacterium Bacillus thuringiensis which produces a protein
poisonous to the European corn borer, an insect that damages
corn crops.
genome of Bt corn
the genetically modified
papaya is resistant to X a plant
virus spread predominantly by aphids.
Papaya Ringspot Virus (PRSV)
is produced by introducing a protein from the PRSV into
plant tissue, which confers resistance to the virus.
The Rainbow papaya
variety
is an herbicide widely used to kill weeds.
Glyphosate
was developed to address dietary vitamin A shortages in the
developing world
golden rice
are genetically engineered to silence the apple gene
responsible for browning due to superficial damage.
Arctic
Apples
are the individuals, organizations, communities,
agencies and governments with a vested interest in the issue.
Stakeholders
also include non-human entities such as the
environment itself, or specific environmental resources.
Stakeholders
everyone who has a vested interest in the food supply
Stakeholders
is an experimental technique that uses genes
to treat or prevent disease.
gene therapy
this technique may
allow doctors to treat a disorder by inserting a gene into a
patient’s cells instead of using drugs or surgery
gene therapy
Researchers are testing several approaches to gene therapy,
including:
Replacing, inactivating, and introducing a new gene
the technique
remains risky and is still under study to make sure that it will
be safe and effective.
gene therapy
is designed to introduce genetic material
into cells to compensate for abnormal genes or to make a
beneficial protein.
gene theraphy
they can
deliver the new gene by infecting the cell.
vectors
viruses that integrate their genetic material (including the
new gene) into a chromosome in the human cell.
retroviruses
viruses that introduce their DNA into the nucleus of the cell, but
the DNA is not integrated into a chromosome.
adenoviruses
can be injected or given intravenously (by IV)
directly into a specific tissue in the body, where it is taken up
by individual cells.
vector
Gene therapy could be
targeted to egg and sperm cells (germ cells), however, which
would allow the inserted gene to be passed to future
generations. This approach is known as
germline gene
therapy
