High-Resolution Imaging using Electron Microscopy and Focussed Ion Beam Cross-Sections
Background of the research
Different research topics need the visualisation and inspection of small structures.
Description of the request (small request)
- Nanometer resolution imaging with Electron Microscope
- See "into" material by making local cuts with a Focussed Ion Beam
Results
High resolution images of different materials and structures are shown below to give an idea about the possibilities.
Laser ablation of a PDMS catheter for controlled drug release
Background of the research
This was a request from bioMMeda, the research group on Biofluid, Tissue and Solid Mechanics for Medical Applications.
Description of the request (small request)
- Perforations in a PDMS catheter (the catheter is a tube with inner diameter of 1mm and 0.4mm wall thickness)
Results
The perforations were made by laser ablation, using the pico- and femtosecond laser setup.
Fabrication of a microwell-based tissue culture platform
Background of the research
This was a request from the Tissue Engineering and Biomaterials research group.
Description of the request (medium request)
- Fabrication of a (negative) PDMS mold to produce a microwell-based tissue culture platform
- This PDMS mold should contain micro-sized cylindrical sticks
Results
Optical microscopy images and a 3D profile measurement of the fabricated PDMS mold are shown below.

Placement and interconnection of a photodiode chip
Background of the research
This was a request from the Electromagnetics research group. They are designing an opto-electric antenna in which a photodiode is compactly integrated onto a dedicated antenna. This work is performed in the context of the ATTO project.
Description of the request (small request)
- Reflow soldering of a chip inductor onto a PCB
- Gluing a packaged photodiode chip on top of the PCB (dimension of about 900 µm x 300 µm)
- Connecting the photodiode chip through two bonding wires.
Two assembled PCBs were needed .
Results
The result after components placement and wirebonding can be seen in the figure below. The assembled PCB was functional and the measurements to study the characteristics of the matching network were performed.
Future work
In a next step NaMiFab will assist in the optical connection between the photodiode and a multimode fiber so that an optimal light coupling is obtained. If this prototype performs well, a paper will be written about this hardware.
Silicon microstructure for Light Sheet Microscopy
Background of the research
This was a request from the Laboratory of General Biochemistry and Physical Pharmacy. One of there research topics focuses on the development of advanced light microscopy methods for functional imaging. The use of Light Sheet Microscopy gains increasing interest but requires a complex optical setup.
Description of the request (large request)
- Co-development of a relatively simple silicon microstructure to simplify the optical setup for Light Sheet Microscopy.
Results
The pictures below show the realised silicon microstructure and a schematic representation of its use in the optical setup.
Fabrication of a stretchable and textile integrated LED display
Background of the research
- This display was developed in the frame of a BIR&D award winning multidisciplinary master thesis
- The resulting "party shirt" was used by the IPEM institute for systematic musicology.
Description of the request (large request)
- A (low resolution) RGB LED display
- Integrated in a T-shirt (battery powered)
- Remotely controlled
Results
Some pictures of the produced stretchable display are shown below.
