Unique Capabilities at PTS

Access to R&D personnel with expertise in:

01 - Post-polymerization modification of polymers by introduction of functional groups for controlled and orthogonal couplings.

Synthesis of different modified linear polymeric architectures based on polyglutamates and PEG

Our methodology allows for the incorporation of various functionalities by “post?polymerization modification”, thereby forming different reactive groups in the side chains of the polymers. This functionalization strategy allows adjustment of the pharmacological properties of each case to the use thereof in drugs or molecular imaging agents with therapeutic and/or diagnostic application.

02 - Taylor-made Polymer-based Drug Delivery Systems for Therapeutic, Imaging or Dermocosmetic applications


Polymer Chemistry: Development of novel biodegradable polymeric carriers with defined architecture (linear, block-copolymers, star polymers). Synthesis and exhaustive characterization:

- To be used for intracellular or extracellular drug delivery of Low Mw drugs, peptides, proteins and siRNAs

- Also molecular diagnostics (probe conjugation)

Bioconjugation Techniques

- Development of ‘New Chemical Entities’ with improved therapeutic value starting from either new discovered or well-known drugs with specific limitations (solubility, pharmacokinetics, etc)

- Rational design of nanoconjugates, mainly focused on the linking chemistry.

- Polymer combination therapy, looking at drug synergism or specific targeting.

03 - Physicochemical characterization of active compounds or complex systems

01- Gel Permeation Chromatography

02- Dynamic Light Scattering

03- HPLC

04- Circular Dichroism

05- H-NMR analysis

04 - Biological evaluation of nanopharmaceuticals,in vivo & in vitro

01- Endocytosis / Cell trafficking
(Qualitative and Quantitative methods)

02- Protein Expression analysis by western blot

03- Cell viability/Cytotoxicity

04- Cell viability/Cytotoxicity

05 - Nucleic Acid Delivery Systems

Existing Biological Barriers for Nucleic Acid Delivery

- Nuclease degradation
- Low half-life
- Negatively charged
- Hydrophilic character
- Difficulties to cross the plasma membrane


PGA-based nucleic-acid-delivery systems are able to bind to nucleic acids, protect the nucleic acids from enzymatic degradation, promote cellular uptake and promote nuclear entry of the pDNA.
