Understanding nanoparticle-cell interactions at single-nanoparticle and single-cell resolutions is crucial to improving the design of next-generation nanoparticles for safer, more effective, and more efficient applications in nanomedicine. This review focuses on recent advances in the continuous high-throughput analysis of nanoparticle-cell interactions at the single-cell level. We highlight and discuss the current trends in continual flow high-throughput methods for analyzing single cells, such as advanced flow cytometry techniques and inductively coupled plasma mass spectrometry methods, as well as their intersection in the form of mass cytometry. This review further discusses the challenges and opportunities with current single-cell analysis approaches and provides proposed directions for innovation in the high-throughput analysis of nanoparticle-cell interactions.

Neuronanomedicine harnesses nanoparticle technology for the treatment of neurological disorders. An unavoidable consequence of nanoparticle delivery to biological systems is the formation of a protein corona on the nanoparticle surface. Despite the well-established influence of the protein corona on nanoparticle behavior and fate, as well as FDA approval of neuro-targeted nanotherapeutics, the effect of a physiologically relevant protein corona on nanoparticle-brain cell interactions is insufficiently explored.

Poly(lactide-co-glycolide) (PLG) nanoparticles loaded with doxorubicin have reached phase-I clinical trials for treating advanced solid tumors. This study explores cell hitchhiking, where nanoparticles associate with blood cells and investigates the impact on pharmacokinetics and tumor migration. Previous findings highlighted the early post-injection phase dominated by nonspecific nanoparticle-cell interactions and burst release.

Background: Raman tweezers spectroscopy (RTS) is a powerful tool that combines optical tweezers and Raman spectroscopy to study single living cells. RTS has become increasingly popular in biomedical and clinical research due to its high molecular specificity and sensitivity, which enable the study of cell viability, cell deformation, cell-protein, cell-nanoparticle, cell-cell interaction, etc. In transfusion medicine, RTS can give valuable insights into the storage lesions and effects of various preservatives and intravenous fluids on blood cells.

Orally administered nanocarriers play an important role in improving druggability, promoting intestinal absorption, and enhancing therapeutic applications for the treatment of local and systemic diseases. However, the delivering efficiency and cell response in mucosa to orally administered nanocarriers is affected by the physiological environment and barriers in the gastrointestinal tract, the physicochemical properties of the nanocarriers, and their bidirectional interactions. Goblet cells secrete and form extracellular mucus, which hinders the movement of nanoparticles.

Neuronanomedicine is an emerging field bridging the gap between neuromedicine and novel nanotherapeutics. Despite promise, clinical translation of neuronanomedicine remains elusive, possibly due to a dearth of information regarding the effect of the protein corona on these neuronanomedicines. The protein corona, a layer of proteins adsorbed to nanoparticles following exposure to biological fluids, ultimately determines the fate of nanoparticles in biological systems, dictating nanoparticle-cell interactions.
