Flow cytometry

Introduction Flow cytometry is a widely used method in biomedical research and increasingly also in clinical diagnostics. It is a powerful and rapid technique to analyze physical and chemical properties of single cells or particles as they are suspended in liquid and pass in a narrow line across laser beams. Fluorescence together with scattered laser light is then filtered, detected, and analyzed on the other side of the sample. In… READ MORE

Photothermal therapy with platinum nanoparticles

Photothermal therapy efficiency Human ovarian cancer cells were plated on Petri dishes and incubated with platinum nanoparticles of varying sizes between 30 and 70 nm. After 24-hour incubation, irradiation was performed using a Modulight ML6600 laser at 808 nm together with an illumination kit (MLAKIT) tailored for Petri dish illumination. A small area of the dish was illuminated with the laser for five minutes with 45 W/cm2 irradiance. Calcein cell… READ MORE
