Microfabrication

Scriba has a decennal experience in microfabrication. Our strengths are the complete customization of our systems, based on customers’ demands, flexibility and a quick answer to customers feedback.

Micro-devices are fabricated on request. Among our customers we list many prestigious universities, research centers, and companies in Europe.

Lists of our products:

  • Microfluidic devices
  • Microelectrodes
  • Working prototype made with a 3D printer, e.g. tridimensional scaffold for cell growth, microfluidic devices connectors, masters, etc.
  • Masters for replica molding
  • Flexible or rigid molds for soft lithography and imprinting
  • Film patterning of polymeric films on large scale
  • Materials patterning

If you are looking for something not on the above list feel free to contact us. We will find the best solution for you

Facilities and Fabrication 

Scriba facilities dispose of two versatile instruments for prototyping:

  • IR laser Marker
  • 3D printer. 

All the fabrications are made based on the customers' requests, which can provide to Scriba the design of the desidered object. Also Scriba can directly design and draws the object based on customers' needs and suggestions. After the final approval we directly fabricate the prototype. 

Here are presented some of our fabrications:

Microfluidic Devices

Scriba’s microfluidic devices have been successful employed in: interfacing of fluids for opto-electronic sensors, cells containing fluids in XRD, GIXD and SAXS (synchrotron included) experiments, imaging with optical and scanning probe microscopes, chemical reaction studies in confined environment for nano- and pico-liters solution volumes, microfluidics circuits for biological testing, micro-reactors for proteins crystallization, devices for quantitative analysis in nano-toxicology fields.

The devices are virtually prototyped employing the finite element calculation method integrated in the COMSOL-FEMLAB software, and hence they can be optimized on customers’ requests.

We can integrated the microfluidic devices on customers’ chosen substrates and make accurate seal testing of the whole system. Seal testing can be made also with a peristaltic pump, which allows for direct and precise control over the speed and the volume of the fluid passing through the microfluidic device. Each fabricated device can be provided, on request, with a complete data sheet.

 

 

Microelectrodes

Scriba has developed an innovative fabrication method of gold, silver and platinum microelectrodes. They can be fabricated on different substrates, rigid, like quartz and glass or flexible, like PET and PEN. Scriba’s microelectrodes can be easily fabricated with different parameters of width (W) and length (L) and also with different geometries, linear, interdigitated or personalized on customer’s request.

The peculiar fabrication process developed at Scriba make the microelectrodes especially suitable for all micro-electronic devices in which is desirable an high output current with a low applied voltage.  Typical applications are Organic Field Effect Transistors in water environment (EGOFET) for sensing devices

 

 

Mold and Replicas

We can fabricate rigid molds and flexible replicas designed according to our customer’s specification. We can add personalized details of micro and sub-micrometric scale.

The molds we produce are generally used for flexographic printing of inks, solutions and formulations, for fabrication of composite molds, for replica molding and imprinting

Our replicas can be integrated on test patterns, metallic substrates, microscope  slides, silicon wafer, polymeric sheets, thin films, even multilayered, and custom substrates. .

We can provide characterization by optical and atomic force microscope of every mold and replica. We can also add various surface treatments (adhesive, anti-adhesive, protective) on the mold surface on customer request.

 

 

Patterning

We can pattern of multifunctional material at the micro- and nanoscale: metallic precursors, clusters of different origins, nanoparticles, polymers, soluble organic materials, biomolecules and soft matter, graphene, nanotubes, and fibrils.

All the patterns are provided with optical and AFM characterization on request.
