Speaker: Dr Francesca Ruggeri, IBM Zurich


  • Nanopatterning creates a 2D landscape for nanoparticle trapping in solution
  • Transport and manipulation of nanoparticles and biomolecules in a nanofluidic slit
  • Assembly of nanoparticles with high accuracy
  • Control on the orientation of asymmetric nano-objects
  • Sorting of nanoparticles with nm-precision


Presentation: 30 min

Q&A: 15 min



We present a method for nanoparticle assembly based on geometry-induced electrostatic trapping inside a nanofluidic slit. One side of the slit is made of glass, whilst the other is a polymer surface patterned with t-SPL. The electrical double layer translates the topography into an effective electrostatic potential, used to trap and manipulate nano-objects within the slit such as nanospheres and biological membranes. The interaction potential increases upon reduction of the slit height until the nano-objects jump into contact with the polymer surface with an accuracy of < 10 nm to the target sites and control over their orientation.

Webinar Series description

The “NanoFrazor Technology” webinars will explain the main features and limitations of NanoFrazor lithography. They will be hosted by the key experts of our R&D teams. You will learn how our technology works, and where and why it is superior or inferior to conventional nanolithography techniques. We will also share the results and insights of our ongoing development projects.

The “NanoFrazor Applications” series will show examples from different application fields, where the NanoFrazor was used to fabricate unique nanopatterns and devices. The guest speakers - scientists who actively use NanoFrazor - will talk about their work and recent results.

The “NanoFrazor Sales” webinars will focus on NanoFrazor products. We will talk about hardware components and software features of the NanoFrazor systems. We will also cover the cost-of-ownership and how to receive a quick return on investment. Finally, we will also offer a dedicated webinar where you will learn about the various funding options for NanoFrazor systems and how to maximize your chances to get your funding proposal accepted.


Test yourself and win! After each webinar, you can test what you have learned in a short multiple-choice questions challenge. With 10 or more successful tests, you will receive a small prize and a unique Nanofabrication Guru certificate.
