Pulling the Terahertz "strings" for label-free molecular fingerprint detection
- Details
Introduction
Biomolecular sensing is an extremely attractive area for terahertz technology, since many characteristic spectral features of biomolecules can be found in the THz frequency range which offer the fundamental possibility of label-free biomolecule detection. However, the large amount of (identical) sample material which is needed for a sufficient contrast - if usual diffraction-limited (far-field) spectroscopy approaches are used - has been identified as a major problem very early [Brucherseifer et al. 2000].

TeraCube M2-R scanner system for chip integrity testing
- Details
Ensuring chip integrity is an increasingly important topic with global reach. The Florida Institute for Cybersecurity Research at the University of Florida has been working in this field for many years and is a pioneer in the development of new test methods for the detection of security-relevant modifications in e.g IC's or chip-packages. Among their latest tools for chip integrity testing, a TeraCube M2-R system was recently installed and commissioned.

High-resolution THz imaging of plants reaches the cellular level for in-situ analysis
- Details
The TeraSpike near-field microprobe series has been applied in the past for the investigation of organic tissue samples. It is known that the THz frequency range is very usefull for biological and medical applications because of its high sensitivity to water-contents and its spectral sensitivity to selective biomolecule absorbtion lines. Thanks to the sub-wavelength spatial resolution provided by our microprobe sensors even cellular details have been made visible in different studies.

Graphene-based flexible electronics are taking advantage of TeraSpike microprobes
- Details
Graphene is widely regarded as a promising material for the fabrication of flexible electronic. Inks or dispersions of Graphene can be deposited on flexible substrates by large-scale coating techniques, such as inkjet printing and spray coating. However, inhomogeneity of the obtained conduction layers is one of the main issues developers are currently facing.

Dutch researches demonstrate TeraSpike at optically excited semiconductors
- Details
One of the most important applications of the TeraSpike probe lies in the field of wafer analysis. So far, it has been mainly used to probe wafer material properties such as sheet resistance or charge carrier mobility under normal ambient conditions. Now a team of researchers from the Dutch institutes DIFFER and Eindhoven University of Technology succeeded in demonstrating the use of the TeraSpike near-field probe for measurements of wafer conductivity under short pulse optical excitation.
