Special Issue Information

Synchrotron radiation from accelerators has been widely used in various biological fields as a quantum tool with an energy region from UV to X-rays. In addition to numerous protein crystallography studies, which have been performed from early on in the development of the technique, recent advances in low-emittance third-generation storage rings can now provide a high-quality photon beam for experiments revealing the properties of biological materials. The energetically monochromatized photon beam allows particular electronic states of biological molecules to be targeted. In particular, spectroscopic techniques with high-energy resolution have been used to accumulate evidence of the physicochemical processes involved in radiation damage to DNA in order to understand the mechanism of mutation and cancer induction. The use of spatially focused X-ray microbeams can target not only particular cells in organs but also specific organelles in living cells. This could be used as a new method to manipulate cell functions or to observe cellular responses to radiation stress. Combined with a photoelastic modulator, the high-frequency switching of circular polarizations is used in the vacuum UV region. This technique has been used to obtain circular dichroism (CD) measurements over a wide wavelength range from vacuum UV to visible light and could be applied to reveal the secondary structures of non-crystallized biomolecules in solution or under biomimetic conditions. The structural changes caused by epigenetic modification, such as phosphorylation of proteins, are also potential CD targets. Furthermore, the coherence of the X-rays obtained in the third-generation facilities and in X-ray free-electron laser facilities is expected to elucidate inhomogeneous structures and their dynamics in living cells. Preliminary studies are in progress. This Special Issue reports the frontiers of biological research using synchrotron radiation.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Quantum Beam Science is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) is waived for well-prepared manuscripts submitted to this issue. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
