Gene Delivery

Trends in Biotechnology
Electrotransfer for nucleic acid and protein delivery

Aswin Muralidharan, Pouyan E. Boukany

Trends in Biotechnology, 2024

Article

We reviewed the latest trends in electrotransfer of nucleic acids and proteins.

Bioelectrochemistry
New insights into the mechanism of electrotransfer of small nucleic acids

Rūta Palepšienė, Aswin Muralidharan, Martynas Maciulevičius, Paulius Ruzgys, Sonam Chopra, Pouyan Boukany, Saulius Šatkauskas

Bioelectrochemistry, 2024

Article

We performed a fundamental study of mechanism of co-electrotransfer of oligonucleotides and siRNA simultaneously with plasmid DNA.

Polymer Chemistry
Nucleophile responsive charge-reversing polycations for pDNA transfection

Reece W. Lewis, Aswin Muralidharan, Benjamin Klemm, Pouyan E. Boukany, Rienk Eelkema

Polymer Chemistry, 2023

Article

We developed charge-reversing polycations which can encapsulate DNA and release it at nucleophilic environments. We further demonstrate evidences that these polycations could potentially be used for gene transfection applications.

Bioelectrochemistry
Models of electroporation and the associated transmembrane molecular transport should be revisited

Maria Scuderi, Janja Dermol-Černe, Clarissa Amaral da Silva, Aswin Muralidharan, Pouyan E. Boukany, Lea Rems

Bioelectrochemistry, 2022

Article / Code

After a critical evaluation, we discovered that existing models are insufficient to simulate the transmembrane transport associated with electroporation and hence must be revisited.

Bioelectrochemistry
Microtrap array on a chip for localized electroporation and electro-gene transfection

Aswin Muralidharan, Georg R. Pesch, Hendrik Hubbe, Lea Rems, Mahdiyeh Nouri-Goushki, Pouyan E. Boukany

Bioelectrochemistry, 2022

Article / Code

We developed microtrap electroporation, and it works better than conventional bulk electroporation to deliver exogenous biomolecules.

bioRxiv
Intracellular transport of electrotransferred DNA cargo is governed by coexisting ergodic and non ergodic anomalous diffusion

Aswin Muralidharan, Hans Uitenbroek, Pouyan E. Boukany

bioRxiv, 2021

Preprint / Code

We tracked electrotransferred DNA cargo transport inside mammalian cells and discovered that it is not the DNA size, but what it encounters in the cytosol that governs its intracellular transport.

Actin networks regulate the cell membrane permeability during electroporation

Aswin Muralidharan, Lea Rems, Michiel T. Kreutzer, Pouyan Boukany

Biochimica et Biophysica Acta - Biomembranes, 2021

Article

We revealed that actin networks increase the energy barrier of electroporation, challenging the traditional view that only lipid bilayer membranes are involved in maintaining cell membrane electropermeability.

Soft Matter
DNA translocation to giant unilamellar vesicles during electroporation is independent of DNA size

Shaurya Sachdev, Aswin Muralidharan, Dipendra K. Choudhary, Dayinta L. Perrier, Lea Rems, Michiel T. Kreutzer, Pouyan Boukany

Soft Matter, 2019 (Inside front cover)

Article / Cover

We showed that electrotransfer of DNA to giant unilamellar vesicles is independent of DNA size.

Scientific Reports, 2019

Article

We showed that actin networks inside vesicles increase the resealing time after electroporation. Furthermore, the actin networks depolymerize during electroporation.
