Particle Size and Shape Analysis
When size matters: Analysing the effect of particle size on bioactivity
Three new research reports explore the often unpredictable relationship between particle size and biological activity, and examine the properties of differently sized particles on (i) the therapeutic index of inhaled drugs, (ii) the lymphatic drainage of vaccine nanoparticles, and (iii) the phagocytosis of microparticles by macrophages.

Reflections of a particle analyser: Using attenuated-total-reflection (ATR) for particle size determination
Researchers in Japan have developed a theoretical framework to apply attenuated-total-reflection (ATR) for particle size determination, potentially opening the door for more routine use of this infrared spectroscopy technique.

Scaling up atomisation: Changes in particle size distribution from pilot to production phase
Danish researchers investigate particle size as a parameter in the scale-up of spray-drying, and find noteworthy differences in size distribution when switching from a pilot-scale to a production-scale atomizer. The lesson? Think big, but experiment first!
