Feasibility study on detection of porphyrin′s amount in human blood based on THz spectrum

Objective To study the feasibility of detecting porphyrin′s amount in human blood based on THz spectrum.Methods Three kinds of porphyrin compounds were synthesized and their THz transmission spectra were measured via a standard system of THz time-domain spectroscopy.Results Porphyrin compound had rich absorbing peaks in the frequency range of 0.1-1THz.Conclusion It is feasible in principle to detect porphyrin via the THz spectrum.
