Effect of Terahertz Waves on the Structure of the Aβ42 Monomer, Dimer, and Protofibril: Insights from Molecular Dynamics Simulations

Bulbil initiation: a comprehensive review on resources, development, and utilisation, with emphasis on molecular mechanisms, advanced technologies, and future prospects

“…THz is intimately linked to the physiological and biochemical processes in plants and provides a potent tool for delving deeper into plant growth, development, and responses to environmental challenges (Li, 2022). Terahertz waves occupy a unique position in the electromagnetic spectrum, falling between microwaves and infrared radiation with wavelengths ranging from about 0.1 to 1 mm (Chen et al, 2023c;Zhang et al, 2023c). What makes THz technology particularly intriguing in the fields of biology and medicine is its non-invasive and radiation-free capacity to detect molecular and cellular changes (Tan et al, 2019;Zhou et al, 2019).…”

Effect of terahertz waves on the aggregation behavior of neurotransmitters

“…18,19 Among these tools, non-invasive terahertz (THz) waves have emerged as a novel way to modulate neural behavior. [20][21][22][23] Theoretical and experimental explorations have assessed the feasibility of modulating biological functions using electromagnetic fields in the mid-infrared spectrum, overlapping with the vibrational spectra of biomolecules, [24][25][26][27][28] with a particular focus on the impact of vibrations on individual chemical bonds. For example, Wu et al 26 discovered that THz stimulation at 44.0 THz could accelerate the unwinding process of DNA molecules and significantly reduce their melting temperature.…”

“…Li et al 27 found that THz stimulation at 42.55 THz could accelerate the permeation of calcium ions in calcium channels. Very recently, Chen et al 28 observed that THz waves at a frequency of 42.55 THz enhance intramolecular interactions in the Aβ42 monomer and intermolecular interactions in the dimer and tetramer, resulting in stronger associations. In general, when molecules are exposed to electromagnetic radiation matching their vibrational frequency, they absorb energy from the radiation, leading to an increase in their vibrational amplitude.…”
