Host defense to RNA viruses depends on rapid intracellular recognition of viral RNA by two cytoplasmic RNA helicases: RIG-I and MDA5. RNA transfection experiments indicate that RIG-I responds to naked double-stranded RNAs (dsRNAs) with a triphosphorylated 5' (5'ppp) terminus. However

Ionic gelation is the most frequently used method to obtain chitosan-tripolyphosphate nanoparticles due to its simplicity and because it does not generate waste solvents in the samples prepared. This paper presents a study of the physical factors involved in this
Chih-Hui Yang et al.
Electrophoresis, 33(21), 3173-3180 (2012-09-06)
This study reports a facile method for the synthesis of hemispherical and discoidal chitosan microparticles by a combination of microfluidic technology and gelation strategy at an oil/water interface. Utilizing microfluidic emulsification in a cross-junction channel, the formation of regular droplets
