POSTDOC FELLOWSHIP: Enzyme-loaded Multiple Coacervate Emulsions
Supervisors: W Loh (UNICAMP) 


This Project aims at preparing and characterizing multiple polymeric coacervate emulsions, which will be selectively loaded with enzymes. Polymeric coacervates should be selected based on their affinity to ensure immiscibility and emulsion characteristics will be evaluated using varied microscopy techniques. Enzyme affinity for each phase will be screened using isothermal titration calorimetry. The evolution of each phase and of the coacervate droplets will be tuned aiming at reproducing (proto)cellular processes and with the purpose of achieving moving actuators responsive to specific targets. Overall emulsion stability will be optimized using Pickering protocols. Experience with microfluidics is also relevant for future applications of the selected emulsions.

Deadline: July 1st, 2024 | Start: ASAP | Salary: BRL 9,047.40/mo


POSTDOC FELLOWSHIP: A Bioinspired Mucociliary Clearance System Based on Mucin-Mimetic Supramolecular Glycopolymers and Artificial Magnetic Cilia for Human Airway Stents  

Supervisors: W Loh (Unicamp), CG Otoni (UFSCar) & R Kieltyka (Leiden Univ)


This is an international collaboration project founded by FAPESP and NWO, led by Profs Watson Loh (IQ-UNICAMP) and Roxanne Kieltyka (Leiden University, NL), including researchers from INCOR/USP, DEMa/UFSCar, ICTSJC/Unifesp, ICT/UNESP, and Fundação Adib Jatene in Brazil, and Delft University, NL). 

This project aims at the development of synthetic mimics of the functional components involved in mucociliary clearance based on mucin-inspired supramolecular glycopolymers and artificial magnetic cilia that can be activated by an external magnetic field. We will explore the synergy between these synthetic components on the movement of mucus out of a tubular configuration for its eventual use in tracheal stents that consist solely of silicone-based tubings. The upgrade of these medical devices to an active, biomimetic platform is anticipated to reduce biofilm formation and infection due to the regenerable surfaces provided by the supramolecular polymers and the beating of the artificial cilia through their magnetic actuation. 

The highly interdisciplinary nature of the proposal and matched expertise of the consortium on the Brazilian and Dutch sides, with support from medical centers and a non-profit organization, will facilitate the development of this bioinspired platform for mucociliary clearance from the molecular to the macroscale for tracheal health. This project should build on early investigations from this group (, and potential candidates should present a strong background in polymer science, preferably with expertise in polymer processing, modification, and characterization techniques. The selected candidate will coordinate efforts from both Brazilian and Dutch teams and is expected to spend an internship in Leiden.
