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:

Mid-infrared versus far-infrared (THz) relative intensities of room-temperature Bacillus spores
TL;DR: In this article, the mid-IR and far-IR spectra of the sporulated form of five Bacillus bacteria were simultaneously recorded from ∼8 to 6000 cm −1 using spore counts on the order of 10 9 deposited onto windows transparent in both the mid and far infrared.

Integrated diffractive terahertz elements
TL;DR: In this article, the femtosecond laser machining with high-energy pulses is used for fabrication of diffractive elements in LiNbO3 crystalline samples, which permits terahertz generation, frequency dispersion, detection, and analysis within a single integrated platform.

A Study of the Effect of a Protein on the Structure of Water in Solution Using Terahertz Time-Domain Spectroscopy:
TL;DR: A comparison between the values of model parameters of solutions with BSA and without BSA allowed to conclude that the main effect of BSA is the formation of strongly bound hydration shells in the immediate proximity to the protein molecule.

Narrow THz Spectral Signatures Through an RNA Solution in Nanofluidic Channels
TL;DR: In this paper, double-stranded, small-interfering (si)-RNA (20-25 bp) samples suspended in buffer solution and confined to the channels of a nanofluidic chip having channel dimensions ~600 × 500 nm and a pitch of ~1.2?m.

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.

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.
