Nanomedicines Characterization Core Facility (NCore)

Due to necessary ceiling restorations from Monday, May 6th, 2024, to Monday, August 1st, 2024 the following changes will take place.

  1. DLS, ZetaView and HPLC equipment will be relocated to Marsico 2219 to ensure continued access and will operate as usual starting May 6th. You will have access if your badge has access to NCore. Marsico 2219 is within the same building and floor, on the other wing.
  2. ICP-MS would be partially accessible during this time, please contact Dr. Sokolsky ( with your sample requests.
  3. All other equipment will not be accessible.

The Nanomedicines Characterization Core Facility implements the CNDD mission of accelerating translation of new nanomedicines into clinic by providing comprehensive physicochemical characterization of nanoscale entities.

NCore is an open resource and functions on a fee for service basis. We welcome users from academia as well as from industry, government labs and other institutions to utilize our experience and our technological infrastructure. We offer:

Nanoparticles fabrication:

Exosomes isolation and characterization:

Analytical analysis:

  • Size, size distribution, concentration, surface chargeDynamic Light Scattering (DLS)Zetaview (ParticleMetrix).
  • Materials analysis (GPC): weight average molar mass (Mw), number average molar mass (Mn), polydispersity, structure: Infra-red (IR), Thermogravimetric analysis (TGA).
  • Analytical capabilitiesHigh Performance Liquid Chromatography, UV-Vis spectroscopy, UV-temperature correlation
  • Protein, peptides, RNA analysisCapillary electrophoresis (protein purity, isoelectric focusing, Glycan analysis, Plasmid/Nucleic Acid purity, heterogeneity and sizing analysis), Automated Western Blot Analysis (Protein Simple), Gel Imager.
  • ICP-MS Elemental analysis: metals analysis in soils, water, food, plants, cells, tissues by ICP-MS.
  • Lyophilization: Benchtop freeze-drying system (Labcono, FreeZone 2.5 Liter).

In Vitro Assays:

  • Protein concentration (BCA assay).
  • Endotoxin contamination (LAL assay).
  • In vitro stability analysis.
  • In vitro drug release analysis.
  • In vitro cellular uptake, transfection and toxicity analysis.

Data analysis and presentation:

  • We offer expert opinion related to study design, sample selection/collection and storage, proposal review and development, manuscript development and review.

NCore collaborates with other Cores on UNC campus (TEM, Proteomics, Flow Cytometry, NMR etc) to facilitate comprehensive analysis of the samples.
