Abstract:
Nature has designed nanosized particles, specifically viruses, equipped to deliver cargo to cells. We report the chemical bioconjugation and shape shifting of a hollow, rod-shaped tobacco mosaic virus (TMV) to dense spherical nanoparticles (SNPs). We describe methods to transform TMV rods to spheres, load TMV rods and spheres with the chemotherapeutic drug, doxorubicin (DOX), to deliver modified particles to breast cancer cells, and to determine the IC50 values of the plant virus-based drug delivery system.

Drug Delivery: Overview
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...
Drug Delivery: Enteral Route
Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
