    In the context of modern healthcare, what is the primary objective of nano-shells or nano-bullets in cancer treatment?

    1. ATo strengthen the patient's bone marrow to withstand high doses of traditional chemotherapy.
    2. BTo act as a diagnostic tool that changes the colour of the patient's skin in the presence of a tumor.
    3. CTo provide targeted drug delivery, ensuring that medication is released only at the site of the cancer cells, thereby minimizing the side effects on healthy tissues.
    4. DTo replace the need for surgery by physically vibrating and crushing the tumor using ultrasonic waves.
    Answer and explanation

    Correct answer: C

    Nano-shells and nano-bullets are designed for targeted drug delivery, carrying the medication straight to cancer cells so it acts at the tumour site and spares healthy tissue. This precision is what reduces the broad toxicity seen with conventional chemotherapy. The other options misstate how these nanoparticles work.
