Development of pro-antibiotic nanocarriers to fight bacterial pulmonary infections


Organic chemistry, fluorescent probe, dye, formulation, emulsions

Description du sujet

The occurrence of multidrug-resistance (MDR) bacteria is on the rise worldwide. In the case of pneumonia, last resort antibiotics can still be active but an increasing number of reports show resistance. In this context, new solutions for the treatment of pulmonary infections due to MDR bacteria, would lies in new antibiotics formulations.
This project aims at developing formulations based on a “pro-drug” approach of an antibiotic combined to efficient biocompatible nanocarriers using fluorescent reporters and florescent imaging.
A 3 years PhD position funded by the ANR-PAANIC is available at the University of Strasbourg. This collaborative and multidisciplinary project involved a co- supervision of the PhD project between two research teams in line with a 10-years collaborative experience in the development of fluorescent nanocarriers for applications in bioimaging and biomedicine (the “Nanochemistry and Bioimaging” laboratory, CNRS in Illkirch, and the “Regenerative NanoMedecine”, Inserm within the CRBS in Strasbourg).
The candidate will have to develop and synthesize pro-antibiotic and fluorescent reporters that will be efficiently encapsulated in lipid nanocarriers. This thesis will mainly include multi-step organic synthesis but also spectral characterizations (absorption and fluorescence spectroscopy), formulation and characterization of nanoparticles, and encapsulation studies.
The candidate will be trained in fluorescence imaging techniques to characterize the diffusion of the nanocarriers in various biomimetic media. The skills aimed to be acquired by the candidate within this PhD research project will be pluridisciplinary, in the field of chemistry and nanomedicine.

Présentation établissement et labo d’accueil

The main objective of our laboratory is through a multidisciplinary approach (combining physics, chemistry, pharmacology, biochemistry, molecular and cell biology) at the different scales of life (from the molecule to the animal) to investigate molecular and cellular mechanisms involved in viral and bacterial infections, and tumor signaling, and to propose new therapeutic clues.
Our laboratory is composed of about 100 persons, including 50 scientists (researchers, University teachers, clinicians, engineers, technicians) and administrative agents, and 50 postdocs, PhD and Master students.
