Our Lab


When we mix polyelectrolytes in a salt solution, this is the precipitate that we get: polyelectrolyte complex that looks like white cheese! We can extrude this into many shapes with our lab extruder

Lab Extruder

We use this extruder to process the “cheese” into many shapes such as rods, tubes, tapes.

Extruder At Work

Producing tubes from polyelectrolyte complexes.

Robot for Preparation of Polyelectrolyte Multilayers

We use this robot to build polyelectrolyte multilayers. Substrates can be fixed on the side or on the bottom, face down, of two rotating shafts that can be spinned at a custom speed.

Little Dog

This small Fourrier Transform Infrared (FTIR) Spectrometer is used to characterize polyelectrolyte thin films and complexes.

Big Dog

This bigger FTIR Spectrometer can be used for normal samples as well as for Attenuated Total Reflectance (ATR FTIR) measurements.

UV Spectrophotometer

The Ultraviolet visible spectrophotometer is used to characterize polyelectrolyte suspensions and complexes, and for turbidimetry measurements.


For quick thickness measurements of thin films.


The dissecting microscope allows imaging of samples with complex surface features.

Vacuum Coater

Plasma Cleaner


Photomultiplier tube (PMT) inside a black box assembled in-house for scintillation counting of radiolabeled polyelectrolyte films and complexes.


Tensile Strength Tester


Rotating Disk Electrode

Spinning disk for zeta potential measurements

This device built in our lab measures zeta potential of surfaces such as polyelectrolyte multilayers.
