Efficient Direct Cytosolic Protein Delivery via Protein-Linker Co-engineering

Francesco Stellacci, Heyun Wang, Lixia Wei, Suiyang Liao

Protein therapeutics have enormous potential for transforming the treatment of intracellular cell disorders, such as genetic disorders and cancers. Due to proteins’ cell-membrane impermeability, protein-based drugs against intracellular targets require eff ...

Influence of structural dynamics on cell uptake investigated with single-chain polymeric nanoparticles

Francesco Stellacci, Arthur Eliot Bouchez, Lixia Wei, Suiyang Liao

Most nanoparticles' parameters affect their interactions with cells. To date, all the parameters studied are basically static (e.g., size, shape, ligands, and charge). This is unfortunate, because proteins have struc-tural dynamics that most nanoparticles ...

Single-Chain Nanoparticles for Intracellular Drug Delivery

Suiyang Liao

Single-chain nanoparticles (SCNPs) are a type of polymeric nanoparticles formed by collapsing/folding individual polymer chains via intra-molecular interactions. Their emergence holds promise to construct sub-20 nm polymeric nanoparticles with defined stru ...

Control and Characterization of the Compactness of Single-Chain Nanoparticles

Francesco Stellacci, Luciano Andres Abriata, Lixia Wei, Suiyang Liao

Polymers when self-cross-linked into single-chain nanoparticles bear some resemblance to folded proteins; yet proteins have clear energy landscapes that determine precisely folded structures, while single-chain polymer nanoparticles (SCNPs) have more undef ...

Comparative characterisation of non-monodisperse gold nanoparticle populations by X-ray scattering and electron microscopy

Francesco Stellacci, Stefan Guldin, Zhi Luo, Ye Yang, Suiyang Liao, Runzhang Qi

Accurate nanoparticle size determination is essential across various research domains, with many functionalities in nanoscience and biomedical research being size-dependent. Although electron microscopy is capable of resolving a single particle down to the ...

Quantification of surface composition and segregation on AuAg bimetallic nanoparticles by MALDI MS

Francesco Stellacci, Zhi Luo, Suiyang Liao

In this work we show that it is possible to use MALDI-TOF as a tool to quantify the atomic composition and to describe the phase segragation of the surface of ligand-coated, bimetallic AuAg nanoparticles. Our investigation shows that AuAg nanoparticles of ...

On the effect of ligand shell heterogeneity on nanoparticle/protein binding thermodynamics

Francesco Stellacci, Ahmet Bekdemir, Suiyang Liao

Nonspecific protein adhesion to nanoparticle (NP) has been proven to have important implications in nanomedicine. However, there are only a few examples of careful studies relating protein binding thermodynamics to NP physicochemical features. In particula ...

Polymeric Micelles Loading Proteins through Concurrent Ion Complexation and pH-Cleavable Covalent Bonding for In Vivo Delivery

Francesco Stellacci, Suiyang Liao

Protein drugs have great potential as targeted therapies, yet their application suffers from several drawbacks, such as instability, short half-life, and adverse immune responses. Thus, protein delivery approaches based on stimuli-responsive nanocarriers c ...
