Characterization of the Aroma Profile of Ginger Powder Produced by a Split-Stream Spray-Drying Process.

Freeze-dried ginger () is renowned for its high quality, but it is expensive. As an alternative, spray drying can be explored for producing ginger powder. However, sugar rich feed solutions can lead to stickiness development during the process.

Synthesis of a Reactive Oxygen Species-Responsive Doxorubicin Derivative.

A heterobifunctional reactive oxygen species (ROS)-responsive linker for directed drug assembly onto and delivery from a quantum dot (QD) nanoparticle carrier was synthesized and coupled to doxorubicin using -(3-dimethylaminopropyl)-'-ethylcarbodiimide hydrochloride (EDC)/sulfo⁻NHS coupling. The doxorubicin conjugate was characterized using ¹H NMR and LC-MS and subsequently reacted under conditions of ROS formation (Cu/H₂O₂) resulting in successful and rapid thioacetal oxidative cleavage, which was monitored using ¹H NMR.
