This question is asked to every candidate, so not specific to my personal situation at all, and therefore is on-topic and meaningful to a person who is seeking to understand what it is like to interview at this company. Glassdoor also literally asks for questions here: Overcoming drug resistance is a major challenge in cancer treatment. In particular, efflux-mediated drug resistance allows cancer cells to transport a wide variety of drugs out of cells, resulting in suboptimal intracellular drug concentrations. To counter this predicament, cutting-edge research is focused on nanotechnology-enabled drug delivery systems aimed at increasing drug concentrations. Thanks to their small size, nanoparticles exhibit disproportionately large surface areas, allowing them to be functionalized with other molecules. Nanoparticles modified with ligands like peptides, aptamers, or other small molecules selectively bind to overexpressed receptors on cancer cell membranes. This action is governed by the principles of molecular recognition. Proteins are even more efficient at targeting key receptors. Unfortunately, successful functionalization depends heavily on the stability and structural integrity of the ligand, so researchers are currently focused on other small molecules. Once functionalized, nanoparticles target cancer cells and release their encapsulated anti-cancer drugs in a controlled manner from within, circumventing efflux pumps. Functionalized nanoparticles can also be engineered to release drugs within specific tumor regions, resulting in hyper localized treatment. However, intratumoral transport of nanoparticles is hindered by inadequate blood supply and elevated interstitial fluid pressure within the tumor. The pursuit of nanotechnology-enabled drug delivery systems remains significant in the field of oncology. Nanoparticles can also be functionalized with imaging agents, such as fluorescent dyes, to improve the sensitivity and specificity of biomedical imaging. How does this process relate to the process described previously?
