Nanotechnology Defense against
Covid-19

2.  Covid-19 is a disease that spread through virus &
attack on human respiratory system.
 A virus is a infectious agent that replicate with
host organism.
Viruses are present in all living organisms including
plants, animals and humans.
 Viruses are also present in bacteria's.
What is Covid-19 & How it
Reacts?
Spherical
Bacteriophage
Helical
Polyhedral
There are basically 4 shapes
of viruses

3. Its scientific name is SARS-CoV-2.
In 2003, SARAS-CoV Spread from China.
 It is called Covid-19 because its first case discover
in 2019.

4. Nanotechnology can play vital role to control the
pandemic Covid-19.

5.  We use bleach, ethanol & chlorheximide as
surface disinfectants but they cause
contamination, material losing and health
problems.
We can use metal nanoparticles such as Silver,
Copper and Graphene as surface disinfectants and
in sanitizers.
Nano Disinfectants
Disinfectant

6.  Nanoparticles have large surface to volume ratio.
 Currently RT-PCR test take time of 48 to 72 hours.
We need rapid detection and reduce time. We can
use gold nanoparticles, Zirconium dots and
graphene.
Nano Detectors

7.  Face masks and gloves are major PPE for the
protection of Covid-19.
Silver nanoparticles has antiviral activity.
Hydrophobic are water
repellent; so their combination
Silver provides best protection &
make also protective by 3D technology.
PPE (Personal Protective
Equipment)
Ag (Silver) + Hydrophobic Best PPE

8.  Copper, Silver and zinc has antimicrobial & anti
viral activity. We can use them as doors etc.
 Copper and silver nanoparticles have toxic effects
for humans due to antiviral activity.
Nano Coatings
Temporary Coating Permanent Coating

9. Nanomaterials range starts from micrometers and
viruses range is also in micrometers.
Some nanomaterial's serve as carrier for antigens
and adjuvant. Viruses attacking part is RNA and
Lipid nanoparticles working region is mRNA.
