In Observance of a U.S. Holiday Agilent Cross Lab/ iLab Operations Software Support Help Desk will be closed during U.S. hours on Wednesday June 19th, 2024. We will resume regular U.S. support hours on Thursday June 20th, 2024. EU and APAC Support will remain open during this time. For urgent matters, please add "Urgent" to the ticket/ email subject or press "1", when prompted, to escalate a call on the iLab Support phone and we will prioritize those requests first.


For system help please email Penn’s iLab support at:

CNSC (Chemical and Nanoparticle Synthesis Core)

Dear Research Community: 

After many successful years, the Chemical and Nanoparticle Synthesis Core will be shutting down. We will not be accepting any more orders. 

Thank you for your support and opportunity to help your research innovation. 

For questions please contact Dr. Andrew Tsourkas at


Overview of Services

The Chemical and Nanoparticle Synthesis Core (CNSC) was established by the Center for Targeted Therapeutics and Translational Nanomedicine (CT3N) to meet the chemical and nanoparticle design and synthesis needs of Penn investigators. The CNSC was formed with support from ITMAT (Clinical and Translational Science Award), the Perelman School of Medicine, the School of Engineering and Applied Science, and the Department of Chemistry (School of Arts and Sciences).

The CNSC supports researchers by providing in-house expertise in medicinal chemistry, metal chelate chemistry, polymer synthesis, and nanoparticle production and surface functionalization. Our chemists provide custom, problem-specific support for researchers in medical, chemical, and materials science fields. Specific services include:

  • Consultation and assistance with the design of chemical/medicinal compounds
  • In-house synthesis of chemical/medicinal compounds
  • Custom nanoparticle design and synthesis
  • Custom nanoparticle surface functionalization (-COOH, -NH2, PEG, -N3, Alkyne, etc.)
  • Polymer and dendrimer Synthesis

In addition to custom services, the CNSC also provides a Catalog of pre-made reactive metal chelates for radiolabeling and other imaging applications, reactive near-infrared imaging agents, hydrophobic and hydrophilic nanoparticles. A list of available products can be found under the ‘Catalog’ pull-down menu on the left.

To schedule an appointment with one of the CNSC chemists to initiate your next CNSC project or to submit a request, please send an email to and we will respond shortly. Please include a brief description of your project, including the chemical structure and amount needed, if known. 

IP and Publication Policy

Intellectual Property (IP): For all projects submitted to the CNSC, the IP will belong entirely to the submitting party, not the CNSC or its employees.

Publications: If the CNSC produces a known chemical compound, nanoparticle, or polymer, we request that the core be acknowledged by the following (or similar) statement: “Compound X was provided by the Chemical and Nanoparticle Synthesis Core, University of Pennsylvania, PA 19104”, with appropriate reference to the published procedure.

If a new compound is produced and complete characterization data is required for publication, we request that the CNSC staff scientist(s) involved with the project be included as a co-author. 

Research Resource Identifier (RRID)

Our RRID is RRID:SCR_022390. Please include this identifer when publishing your results.
