Nanotechnology Tools to Detect SARS-CoV-2
Standard procedures for detecting the virus from nasopharyngeal and/or oropharyngeal swabs have been reviewed recently and are primarily based on reverse transcription polymerase chain reaction (RT-PCR). Here, we would like to mention some preliminary ideas on nanotechnology-based assays to monitor the presence of SARS-CoV-2. A simplified test and variants thereof to detect viral proteins (e.g., HIV or influenza virus) without the need for expensive equipment is based on the color change of Au NPs bound to antibodies. Similar to the enzyme-linked immunosorbent assay (ELISA) antibodies coupled…

Scientific Method and Tools
Pre-Lab Questions:
1. Briefly outline the experiment that will be conducted to demonstrate the scientific method.
2. What are the basic metric units for measurements of length, mass, and volume?
3. Express these two numbers in scientific notation: 580 and 0.00355
4. If you were very thirsty, which bottle of Fiji water would you choose, the 200 ml or 1.5 l?
Introduction: The metric system is used by the international scientific community. Metric units and
some common measuring devices used for those measurements will be reviewed in this lab. Some of
these tools will be used to develop an understanding of the terminology, practice, and application of the
scientific method by performing an experiment. A testable hypothesis and prediction will be formulated,
tested, and data collected and analyzed. The analysis will include the appropriate presentation of data
using a graph to illustrate your conclusions.
Scientific Method: Sponge Animals

Nanotechnology Tools to Inactivate SARS-CoV-2 in Different Environments Outside the Patient
SARS-CoV is highly stable at room temperature and at 4 °C, but it is inactivated by ultraviolet light at 254 nm, highly alkaline or acidic conditions of pH >12 or pH <3, respectively, or by brief (e.g., 5 min) heat treatment at 65 °C. SARS-CoV-2 is expected to be similarly sensitive. Several human coronaviruses can be inactivated by classical disinfectants, including bleach, ethanol, povidone-iodine, chloroxylenol, chlorheximide, and benzalkonium chloride, so we expect similar inactivation with SARS-CoV-2. The virus stability on surfaces…

Qno1) A 45 years old patient comes to you with chief complain of neck pain along with stiffness and the pain radiate to the right shoulder and arm. The patient also complained of headaches at the back of the head just above the neck and travel over the top to the forehead. On Further examination it was noticed that the frequency of the pain increased by cervical movement but the severity of the pain is increasing more by looking up to the ceiling the pain is not relieved by any kind of Rest. The previous history of the patient showed that 3 years back he was involved in major car accident.

Procedure 1 Magnification
Light is refracted through two lenses to obtain magnification-the ocular lens and the objective lens. Magnifi-
cation of the ocular lens is usually 10x.This means that if you were to view a slide with only the ocular lens,
the image would be magnified 10 times. Magnification of the objective lenses varies, but typically is 4× for low power,
10× for medium power, and 40× for high power. (To verify that this is the case for your microscope, look at the side of
the objective lens, which usually is labeled with its magnification.) Remember that oil immersion provides even greater
magnification at 100×. When calculating the total magnification, you must multiply the magnification of the ocular lens
(10) by the power of the objective lens.
Fill in Table 3.1 to determine total magnification at each of the different objective lenses on your microscope.
Remember that the magnification of the objective lens is usually printed on the side of the lens itself.

Supplementary Problems:
Problem 1: At a magnification of 40x, a student measured 41 ocular micrometer divisions
per millimeter. What is the distance, in micrometers, per ocular unit at 40x?
Problem 2: At a total magnification of 100x, a student measures 16.4 ocular micrometer
divisions per millimeter. What is the distance, in micrometers, per ocular unit at 100x?
Problem 3: At a total magnification of 400x, a student measures 4.1 ocular micrometer
divisions per millimeter. What is the distance, in micrometers, per ocular unit at 400x?
Problem 4: Notice the pattern in the above 3 problems. What do you think the distance in
micrometers per ocular unit at 1000x would be?
Problem 5: It was found that the units on the ocular micrometer and the units on the stage
micrometer matched up 40 units to 1.0 mm at 100 power. (So 40 ocular units equals 1.0
mm.) If the wing of a dead fruit fly was measured to be 2.5 ocular micrometer units at a

be at least 10 days and collection period should be 7
days. Collect at least 50 grab samples of faeces
from each animal. To overcome diurnal variation,
collect randomly in the pasture or pen. If more than
one animal is in a pasture, coloured polyethylene
particles may be administered to the animals so that
the faeces may be distinguished from one animal to
another. Diets and faeces samples of individual
lambs were dried separately at 60°C. Chromic oxide
