Delivery efficiency can be measured through various quantitative and qualitative metrics:
Pharmacokinetics (PK): Examines the absorption, distribution, metabolism, and excretion of drugs. Biodistribution: Measures the distribution of the therapeutic agent within the body. Target site accumulation: Assesses the concentration of the drug at the tumor site relative to other tissues. Therapeutic outcomes: Evaluates the efficacy in terms of tumor shrinkage, progression-free survival, and overall survival.
