Hole Scavenging and Photo-Stimulated Recombination of Electron-Hole Pairs in Aqueous TiO2 Nanoparticles [PDF]
arXiv, 2004 It is shown that 532 nm and 1064 nm laser photoexcitation of trapped electrons generated by 355 nm photolysis of aqueous titania (TiO2) nanoparticles causes rapid photobleaching of their absorbance band in the visible and near IR. This photobleaching occurs within the duration of the laser pulse (3 ns FWHM); it is caused by photoinduced electron ...

Advanced Healthcare Materials, EarlyView.Melanoma cell spheroid engraftment is optimized in the chicken chorioallantoic membrane overcoming the complexity of other in vivo models. Using this model, greater penetration of cerium oxide nanoparticles (nanoceria) functionalized with heparin in spheroids is observed via enhancement of vascularization than nanoceria alone.

Local Clustering and Global Spreading of Receptors for Optimal Spatial Gradient Sensing [PDF]
Phys. Rev. Lett. 134, 158401 (2025)Spatial information from cell-surface receptors is crucial for processes that require signal processing and sensing of the environment. Here, we investigate the optimal placement of such receptors through a theoretical model that minimizes uncertainty in gradient estimation.

SR-BI-directed HDL-cholesteryl ester hydrolysis
Journal of Lipid Research, 2003 We have examined the metabolic fate of HDL cholesteryl ester (CE) delivered to cells expressing scavenger receptor class B type I (SR-BI). Comparison of SR-BI with a related class B scavenger receptor, CD36, showed a greater uptake and a more rapid and ...

Simple approach for calculating the binding free energy of a multivalent particle [PDF]
, 2016 We present a simple yet accurate numerical approach to compute the free energy of binding of multivalent objects on a receptor-coated surface. The method correctly accounts for the fact that one ligand can bind to at most one receptor. The numerical approach is based on a saddle-point approximation to the computation of a complex residue.
