The magnetic field in the sample position was measured by a LakeShore 450 Hall probe. Quantification of the BLS signal enhancement To quantify the enhancement of the BLS signal, we developed a simple phenomenological model based on the following equation $${\sigma }_{BLS}(f)={\iint }_{{k...
Poly(lactic-co-glycolic acid) 40–75 kDa) was purchased from Lakeshore Biomaterials (Birmingham, AL). Poly(vinylpyrrolidone) PVP (58 kDa) was provided by Ashland (Kidderminster, UK). Ultrapure water was obtained from a water purification system (Elga PURELAB DV 25, Veolia Water Systems, Dublin...
