TLDR
The first use of pulsed terahertz spectroscopy to examine low-frequency collective vibrational modes of biomolecules was reported in this paper, which indicated that a large number of the lowfrequency collective modes for these systems are IR active.About:

Performance of THz fiber-scanning near-field microscopy to diagnose breast tumors.
Hua Chen,Wen-Jeng Lee,Hsin-Yi Huang,Chui-Min Chiu,Yuan-Fu Tsai,Tzu-Fang Tseng,Jen-Tang Lu,Wei-Ling Lai,Chi-Kuang Sun +8 more
TL;DR: Based on the statistics of 20 female patients, it is demonstrated that the diagnostic sensitivity and specificity of the THz fiber-scanning near-field microscopy to examine breast tumor sections are all as high as 100%.

Picosecond orientational dynamics of water in living cells.
Martijn Tros,Linli Zheng,Johannes Hunger,Mischa Bonn,Daniel Bonn,Gertien J. Smits,Sander Woutersen +6 more
TL;DR: By measuring the rotational motion of water molecules in living cells, Tros et al. find that apart from a small fraction of water solvating biomolecules, cell water has the same dynamics as bulk water.
Journal ArticleDOI
Terahertz pulse spectroscopy of biological materials: L-glutamic Acid.
TL;DR: The terahertz pulse spectra of L-glutamic acid show a number of well-resolved transitions in the 1.75–2.5 THz region, but it was noted that the theoretical model did not include anycrystalline or hydrogen-bonding effects.
Journal ArticleDOI
Highly Sensitive and Selective Detection of Steroid Hormones Using Terahertz Molecule-Specific Sensors.
TL;DR: A label-free type of terahertz molecule sensor capable of sensing and identifying progesterone and 17α-OH-progesterone selectively and much improved by controlling evaporation speed is introduced, resulting in an efficient, homogeneous distribution of the molecules onto a sensing hot spot.

Structure of serum albumin.
Daniel C. Carter,Joseph X. Ho +1 more
TL;DR: This chapter provides an insight of the findings of past significant papers with the current knowledge of the recently determined high resolution X-ray structure of serum albumin and suggests that AFP may have a higher affinity for some unknown ligands important for fetal development.

Collective Variable Description of Native Protein Dynamics
Steven Hayward,Nobuhiro Go +1 more
TL;DR: The normal-mode refinement method of protein X-ray crystallography, which is developed based on the concept of the above important subspace, is discussed and indicates that most important conformational events are taking place in a conformational subspace spanned by a rather small number of principal modes.
