Define nanomedicine and list at least three different applications of nanomedicine.
- 🧠 ANSWER ✔✔Nanomedicine is the use of nano-biotechnology in medicine.
Different applications of nanomedicine include imaging agents and diagnostics,
real-time assessment to accelerate clinical translation, multifunctional targeted
devices, monitoring predictive molecular changes, and research enablers like chip-
based nano-labs.
Name four examples of FDA-approved nanotechnology-based products, and
explain one advantage of using nanocarriers in drug delivery. - 🧠 ANSWER
✔✔Four examples of FDA-approved nanotechnology-based products are
Abraxane, Doxil, Feraheme, and Mycamine. An advantage of using nanocarriers in
drug delivery is the enhanced targeting and delivery of therapeutic agents to
, specific cells or tissues, reducing off-target effects and improving treatment
efficacy.
What physicochemical characteristics influence the toxicity and biodistribution of
nanoconstructs? Provide examples of physical and chemical characteristics. - 🧠
ANSWER ✔✔Physicochemical characteristics influencing nanoconstructs toxicity
and biodistribution include physical characteristics like size, surface area, and
shape, and chemical characteristics like charge, hydrophobicity/hydrophilicity, and
surface chemistry. For instance, a smaller size and a positive charge may increase
cellular uptake, while hydrophobicity can affect solubility and toxicity.
Summarize the findings reported in the research article "Multivalent HER2-binding
polymer conjugates facilitate rapid endocytosis and enhance intracellular drug
delivery." - 🧠 ANSWER ✔✔The research co-opts crosslinking-mediated
internalization for efficient intracellular delivery of an anticancer nanomedicine,
particularly an HPMA copolymer-based drug delivery system. The study
synthesized and characterized HPMA copolymers-affibody conjugates,
demonstrating that higher valence conjugates enhanced intracellular drug delivery
and cytotoxicity against HER2-positive cells.
What polymerization technique was used in the synthesis of polymer conjugates in
the mentioned article, and why is it relevant for drug delivery systems? - 🧠
