Terahertz Time-domain Spectroscopy
By applying the Terahertz time-domain spectroscopy technique, the drug components and water content percentage of cells can be detected from the frequency-spectrum. Meanwhile, the measured time of Terahertz time-domain spectroscopy is fast and without contact. It could also identify drugs with the same chemical formula in different forms.
Terahertz time-domain spectroscopy applies ultra-short terahertz pulse to obtain frequency-spectrum information after converting to a fast flourier transform format. Furthermore, different substances can be used to absorb the specific terahertz wave frequencies for identifying the composition and components of materials. In other words, the Terahertz time-domain spectroscopy technique is fairly suitable for the determination of drugs and cellular components.
Biomedical Image Application
Terahertz is a new biomedical technology, and there are many potential possibilities in this industry. Base on this situation, ACE Biotek is currently working together with Taraview company located in the UK in order to seek if there is any opportunity that can be applied by terahertz technology or in any biomedical research domain.
Terahertz could pass through in different dielectrics, and it will show various characteristics among different signals. We can adjust a wide range of frequencies and expand system application in terms of its flexibly, including biomedical image detection, material properties measurement, and medical-related testing.
3D Imaging Technology
Terahertz signal can be penetrated from dielectric materials; meanwhile, one of the special features of Terahertz is that it has no harm to the human body so it is compatible with the development of medical imaging systems.
By using Terahertz, we are able to scan different materials including images with the depth information. Also, detection of the material results in a non-contact manner that can be applied to human tissue detection is regarded as a new medical material technology development.
Non-destructive Testing Scenario
Terahertz, a type of electromagnetic signal, its’ frequency is between infrared and microwave and has the unique characteristics of non-destructive and high-penetrate on substances. Therefore, it is suitable for the material (components) detection targeting and non-destructive testing.
With two major advantages of Terahertz that are high- penetrate and harmless, it can be widely applied to several research domains such as security, material, food, drug, and poison detection. All of the cases mentioned above can be in a new non-contact and non-destructive biomedical testing system.
