Introduction to Drug Release Monitor Accessory – DRM 

Magnetic heating can be used as a trigger mechanism for on-demand drug release systems. D5 Series Drug Release Monitor (DRM) Accessory determines the in-situ concentration released by smart materials activated remotely using an alternating magnetic field (AMF) with a D5 Series Driver.

Drug Release Monitor Characteristics

DRM is a versatile system that allows user to perform real time monitoring of drug released magnetically activated at different frequencies and field values.

Drug delivery is determined by UV-vis spectrophotometry and can perform trials in many configurations, working with macroscopic samples (e.g. ferrogels) or liquid samples (e.g. magnetic nanoparticles, magnetic liposomes…) depending on the user.

DRM includes two different sample holders for solid or liquid samples to introduce inside the coil.

Drug Release Monitor Features 

Reliable
DRM registers the CONCENTRATION released by smart materials. Absorption and transmission spectrum, characteristic of each drug, is determined on real time by the SPECTROPHOTOMETER. The Software controls both the AMF intensity related with the temperature reached and the concentration released.

Safe
Magnetic nanoparticles are slowed down and retained in the MAGNETIC SEPARATOR, then the FILTER SET stop particles bigger than 10 µm so the sample continues its way into the Z flow and arrives clean at the spectrophotometer.

Versatile
Different SAMPLE HOLDERS are available for solid and/or liquid samples. User is also enabled to operate in DIFFERENT WAVELENGTHS depending on the module and lamp selected and the drugs absorption requirements.

Precise
PERISTALTIC PUMP is activated through the Software, starts taking the sample from the reservoir and pushes it into the circuit. It includes a 10-turn POTENTIOMETER to adjust the PUMP’S SPEED allowing user to calibrate the FLOW RATE in different positions and use this value to calculate the mass release.
