Question No. 1

How to write an email professionally.

Answer:

Writing a professional email is crucial for effective communication in various settings. Here are some key guidelines:

Clear and Concise Subject Line:

• Use a subject line that clearly summarizes the purpose of the email.

• Avoid vague or misleading subject lines.

Formal Greeting:

• Begin with a formal greeting (e.g., "Dear Mr. Smith," or "Hello Dr. Johnson,") unless you have a close relationship with the recipient.

Introduction:

• Start with a brief introduction, stating the reason for your email.

• Provide context if necessary but keep it concise.

Body of the Email:

• Organize your content into paragraphs for readability.

• Be clear and specific about your purpose.

• Use a professional tone and avoid casual language unless the relationship allows for it.

Polite and Professional Language:

• Choose words carefully to maintain a professional tone.

• Use polite language, including "please" and "thank you" as appropriate.

Clarity in Communication:

• Clearly state any requests or actions you expect from the recipient.

• Avoid jargon unless you are sure the recipient understands it.

Closing:

• End with a courteous closing (e.g., "Best regards," "Sincerely,") followed by your full name.

Signature:

• Include a professional email signature with your contact information.

Proofreading:

• Proofread your email for grammar, spelling, and punctuation errors before sending.

Attachments:

• If applicable, mention and attach any necessary files, and provide a brief description.

Question No. 2

How would you develop a coronavirus detection biosensor? It should have following details:

1. Type of biosensor

2. Detection scheme

3. Nanoparticles used for detection

Answer:

Type of Biosensor:

Immunosensor:

Utilize antibodies or antigens specific to the coronavirus to detect the presence of viral particles.

Nucleic Acid Biosensor:

Design biosensors based on detecting viral genetic material (RNA or DNA) using probes complementary to coronavirus sequences.

Detection Scheme:

Surface Plasmon Resonance (SPR):

Exploit changes in the refractive index on a sensor surface due to the binding of viral particles, allowing real-time detection.

Electrochemical Detection:

Measure changes in electrical conductivity resulting from the interaction between viral components and electrodes.

Nanoparticles Used for Detection:

Gold Nanoparticles:

Functionalize gold nanoparticles with specific antibodies for binding to coronavirus antigens, leading to measurable changes in color or conductivity.

Quantum Dots:

Utilize quantum dots as fluorescent markers for detecting viral particles, providing a highly sensitive and quantitative method.

Magnetic Nanoparticles:

Attach magnetic nanoparticles to viral RNA or DNA, allowing for easy separation and concentration of target molecules for detection.

The proposed coronavirus detection biosensor combines the specificity of biosensor types with the sensitivity of advanced detection schemes and strategically chosen nanoparticles for efficient and accurate identification of the virus.
