Explanation:

• The nanotube’s structure allows it to be used as a container for transporting a drug in the body. A molecule of the drug can be placed inside the nanotube cage. This keeps the drug ‘wrapped up’ until it reaches the site where it is needed. In this way, a dose that might be damaging to other parts of the body can be delivered safely to, for example, a tumour.
• Recently, it has been demonstrated that functionalized carbon nanotubes can be degraded by oxidative enzymes . This finding is offering a new perspective for the development of carbon nanotubes in medicine.
• Enabling technology would facilitate the making of nanodevices using these blood-compatible nanomaterials as building blocks for biomedical applications such as artificial implants, including structural tissue replacements, that is, artificial blood vessels, or functional devices such as drug delivery matrices.
• Biochemical Sensors Using Carbon Nanotube Arrays: NASA has successfully demonstrated a miniaturized electronics technology with extremely high sensitivity and simplified sample preparation for in-vitro detecting specific biomarker signatures, which is based on incorporating embedded vertically aligned carbon nanotubes as nanoelectrode arrays in diagnostics devices.

Hence all statements are correct.
