Scientific Highlights and News

graphical abstract

The EIPBN 2021 Best Journal Paper Award was given to the paper "Hybrid structures by direct writing lithography – tuning the contrast and surface topography of grayscale photoresist with nanoimprint", J. Vac. Sci. Technol. B 39 (2021) 052603 (9 pp), with the authors S. Xie, J. Erjawetz, C. Schuster, and H. Schift. It was chosen from papers presented at the 64th International Conference on Electron, Ion, and Photon Beam Technology and Nanofabrication and published in JVST B. It was the first paper that presented novel work of the new direct laser writing tool DWL 66+ that was purchased in the framework of ANAXAM. It combined established nanoimprint lithography with grayscale photolithography. Helmut Schift, as corresponding author, received the award together with Sijia Xie, the first author and presenter at EIPBN, who was postdoc in Helmut Schift's group up to May 2021.

Contact-less micro-polishing

A new method of material modification using 172 nm UV photons enables to fabricate ultra-smooth and self-optimized polymer surfaces. The method, published in Advanced Materials Technologies, was used in the production of high quality micro-optics to remove typical process flaws after a 2-photon-lithography process.

Light-switching of enzymatic activity in functionalized polymer brushes

UV- and visible light-induced switching of enzymatic activity has been demonstrated using surface-grafted polymer brushes functionalized with microperoxidase MP-11 and spiropyran mojeties. Integration into an optofluidic device allowed reversible switching of the enzymatic activity under flow.

Award winner Sahan Ranamukhaarachchi

Technology award for microneedle-optofluidic sensor System

Sahan Ranamukhaarachchi, PhD student from UBC in Vancouver, won the 2016 "Brian L. Barge Award for Excellence in Microsystems Integration" for his work on a biosensing platform with integrated hollow microneedles carried out at PSI in 2015 in collaboration with Dr. Victor Cadarso and Dr. Celestino Padeste.

Therapeutic drug monitoring in sub-nanoliter volumes

A promising system for painless and minimally-invasive therapeutic drug monitoring has been demonstrated. The proposed device combines biofunctionalized hollow microneedles with an optofluidic system to measure drug concentrations in volumes as small as 0.6 nL.

Massstabsgetreues Mikro-Matterhorn

Medienmitteilungen Zukunftstechnologien Materialforschung Mikro- und Nanotechnologie

Forschende des Paul Scherrer Instituts haben in grosser Zahl detaillierte Modelle des Matterhorns erzeugt, die jeweils weniger als ein Zehntel eines Millimeters gross sind. Damit führen sie vor, wie so feine 3-D-Objekte in Serie hergestellt werden könnten. Materialien, deren Oberfläche mit einem Muster aus solchen winzigen 3-D-Strukturen versehen ist, haben oft besondere Eigenschaften, die beispielsweise helfen könnten, den Verschleiss von Maschinenbauteilen zu reduzieren.
