Nanofluidic Systems

Custom-designed systems to study fluids under sub-micrometer confinement for biological research and fundamental polymer science.

Read more

Based on our own work in the field of nanofluidics, the FUEC system has been developed in close collaboration with our customers, aiming at maximizing comfort and flexibility for nanofluidic experiments. The FUEC system comprises framed nanofluidic chips, chip holders, and a pressurizing unit that can be assembled easily. Our nanofluidic chips are custom-designed and typically made of glass, fused silica and glass-silicon composite materials with a high degree of biocompatibility and high resistance to difficult environmental conditions (e.g. aggressive chemicals and/or high temperatures).





Customized TEM membranes

Silicon nitride support films for transmission electron microscopy with integrated components for in situ analysis of reactions and materials at atomic resolution.

Read more

Thin films of low-stress silicon nitride are utilized to create large transparent windows appreciated in transmission electron microscopy (TEM). We offer these membranes as plain or integrated TEM windows with customizable lateral dimensions. Our integrated TEM windows comprise structures such as openings, electrodes, or heaters with a resolution down to sub-10 nm, allowing in situ for atomic resolution during analysis of materials and reactions.





Nanoplasmonic Sensors

Optical sensors based on nanoplasmonics for detecting minute amounts of biological objects and chemicals in a fast and contact-free manner using spectroscopic methods.

Read more

Analytic methods in biology and chemistry strive after ever increasingly sensitivity to meet today's demands in e.g. public health care, catalysis or homeland security. One promising approach is based on optical sensors using nanoplasmonics to detect objects and reagents at extremely low concentration or with upmost selectivity. We offer a wide range of nanoplasmonic sensors fabricated with electron beam or hole-mask colloidal lithography. In general, we can design these sensors in a large variety of shapes, surface coatings, materials or material stacks adapted to your purpose.




Superconducting Single-Photon Detectors

Near-infrared and optical single-photon detectors based on current-biased superconducting nanowires for quantum information and imaging of infrared photoemission.

Read more

Thin-film superconducting nanowires are used for single-photon detection in the near-infrared and visible range of the electromagnetic spectrum. When hitting the active region of such detector, photons are absorbed leading to a local breakdown of the superconductive state in the nanowire. The correlated increase in resistivity can be measured with high temporal resolution allowing for the detection of individual photons. Our superconducting single-photon detectors are based on high-quality niobium nitride films, electron-beam lithography and reactive ion etching, ensuring excellent performance due to sharp phase transitions and minimum line-edge roughness.


With the focus on nanostructures, ConScience offers a wide range of processing and characterization services in cleanroom environment. From development and prototyping to small series production, we offer the opportunity to implement your ideas in nanotechnology.


High Resolution SU-8 Structuring Abilities

We offer sub-50nm nanostructures with high aspect ratios fabricated in the demanding resist SU-8 to create plating molds, MEMS or micro- and nanofluidic devices.

Read more

SU-8 is a negative tone photo resist often applied in thick layers that can be exposed both by UV-light and electrons. Well known for excellent biocompatibility as well as high mechanical and chemical stability, the resist is frequently used in microfluidics and MEMS. Moreover, SU-8 became a popular material in the field of plating due to the possibility to structure the resist at unusual thicknesses. Our processes for SU-8 allow to pattern films of thicknesses from beyond 100µm down to 40nm, keeping critical dimensions as small as 30nm, while offering enhanced adhesion and mixing of nano- and micro structuring. 




Electron Beam Lithography at the Resolution Limit

Processing of sub-10 nm features is achieved by high resolution electron beam lithography and well controlled pattern transfer techniques.

Read more

The use of state-of-the-art electron-beam lithography systems combined with our excellent process control allows for fabricating structures with features in the sub-10 nm regime. Moreover, we are experienced in transferring such high-resolution patterns into thin films or substrates by lift-off techniques or dry etching. For example, we have produced quasi-closed gold films comprising large areas of periodically arranged squares separated by gaps of 6 nm.




Fabrication of Complex Multi-Layer Devices

In-depth process control, detailed fabrication knowledge and thorough working methods allow us to fabricate complex devices with high yield.

Read more

The fabrication of complex multi-layer devices requires rigorous and clean working routines as well as a thorough understanding of all included process steps to achieve high performance and cost efficiency. Our long-standing cleanroom experience and nanofabrication expertise enables us to fabricate such highly integrated complex devices with many different layers such as hot-electron bolometer mixers and Schottky diodes for heterodyne receivers for THz radiation.



Science Writing and Editing

We offer science communication services and we specialise in writing and editing scientific content, in particular popular science news and feature articles. In addition to science journalism assignments, we take commissions concerning technical documents, academic reports and science-related web or blog content

Rounded Sensors

Tuning surface properties of nanoparticles for studies of their interactions with molecules in biological systems.

Read more

Following our customer’s idea to investigate key features of nanoparticles and their effects on biological systems, we developed a protocol that allows for tuning the facet-to-edge ratios of nanoparticles. Particular processing steps comprise hole-mask colloidal lithography and rapid temperature treatments, resulting in quasi-spherical nanoparticles of faceted equilibrium shape. These structures facilitate in-depth studies of the formation of bio-corona on nanoparticles, adding a valuable tool to the portfolio of our costumer in the field of nanomedicine and nanotoxicology.



Narrow gaps etched into a nanodiamond film forming nanopillars reaching a aspect ration of 1:14.

Read more

Due to an increasing availability thin films of nanodiamonds enjoy growing popularity in the research community. In this case our customer required hexagonal arranged and tightly packed nanopillars fabricated from their diamond films. Meeting the request to reduce the distance between adjacent pillars as much as possible we succeeded to etch gaps as narrow as 22 nm in a 320 nm thick film, resulting in aspect ratios exceeding 1:14 for the gaps.



Microfluidic Devices

Especially the small test volumes and the precise manipulation capabilities cause the popularity of microfluidic devices. in the fields of among others biology, chemistry, pharmaceutics and food science.

 Read more

The multidisciplinary field of microfluidics deals with the behavior, precise control, and manipulation of fluids that are geometrically constrained to a small scale, recently used by our costumer to meet the need for fast diagnostics of antimicrobial resistance - a globally emerging problem that threatens our ability to treat common infectious diseases, resulting in prolonged illness, disability, and death. By measuring the physiological response at the level of single cells and averaging over the corresponding population, our costumer could differentiate between resistant and susceptible bacteria within 3-11 minutes, while the golden standard usually takes 2 days to perform.
