For bio application we have to generate an alternating magnetic field of 1.7–2.5 kA/m and frequency 375 kHz. Does this require costly equipment? Where are these types of machines used?
Low Frequency RF pallets with lowcost reliable SMPS modules will help to develope at lowcost
We observed that a triblock copolymer (PEG12-PCL24-PEG12) is more hydrophilic than diblock (PEG12-PCL12). Micelles prepared from the diblock copolymers were less stable and aggregated much faster.
