Abstract
Herein, we present a novel ultrasensitive graphene field-effect transistor (GFET) biosensor based on lithium niobate (LiNbO3) ferroelectric substrate for the application of breast cancer marker detection. The electrical properties of graphene are varied under the electrostatic field, which is generated through the spontaneous polarization of the ferroelectric substrate. It is demonstrated that the properties of interface between graphene and solution are also altered due to the interaction between the electrostatic field and ions. Compared with the graphene field-effect biosensor based on the conventional Si/SiO2 gate structure, our biosensor achieves a higher sensitivity to 64.7 mV/decade and shows a limit of detection down to 1.7 fM (equivalent to 12 fg·mL-1) on the detection of microRNA21 (a breast cancer marker). This innovative design combining GFETs with ferroelectric substrates holds great promise for developing an ultrahigh-sensitivity biosensing platform based on graphene that enables rapid and early disease diagnosis.

Abstract
Using aqueous precursors, we report successfully fabricating thin-solid films of two nucleic acids, ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). We investigated the potential of these films deposited on a fiber optic platform as all-fiber integrated saturable absorbers (SAs) for ultrafast nonlinear optics. RNA-SA performances were comparable to those of DNA-SA in terms of its nonlinear transmission, modulation depth, and saturation intensity. Upon insertion of these devices into an Erbium-doped fiber ring-laser cavity, both RNA and DNA SAs enabled efficient passive Q-switching operation. RNA-SA application further facilitated robust mode-locking and generated a transform-limited soliton pulse, exhibiting a pulse duration of 633 femtoseconds. A detailed analysis of these pulsed laser characteristics compared RNA and DNA fiber optic SAs with other nonlinear optic materials. The findings of this research establish the feasibility of utilizing RNA as a saturable absorber in ultrafast laser systems with an equal or higher potential as DNA, which presents novel possibilities for the nonlinear photonic applications of nucleic acid thin solid films.

Abstract
We have proposed that the abiogenesis of life around the beginning of the Archean may have been an example of "spontaneous" microscopic dissipative structuring of UV-C pigments under the prevailing surface ultraviolet solar spectrum. The thermodynamic function of these Archean pigments (the "fundamental molecules of life"), as for the visible pigments of today, was to dissipate the incident solar light into heat. We have previously described the non-equilibrium thermodynamics and the photochemical mechanisms which may have been involved in the dissipative structuring of the purines adenine and hypoxanthine from the common precursor molecules of hydrogen cyanide and water under this UV light. In this article, we extend our analysis to include the production of the other two important purines, guanine and xanthine. The photochemical reactions are presumed to occur within a fatty acid vesicle floating on a hot (∼80 ∘C) neutral pH ocean surface exposed to the prevailing UV-C light. Reaction-diffusion equations are resolved under different environmental conditions. Significant amounts of adenine (∼10-5 M) and guanine (∼10-6 M) are obtained within 60 Archean days, starting from realistic concentrations of the precursors hydrogen cyanide and cyanogen (∼10-5 M).

[PMID: 30816277 PMCID: PMC6395717 DOI: 10.1038/s41598-019-39616-1] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2018] [Accepted: 01/29/2019] [Indexed: 12/26/2022] Open
Abstract
Adaptation in CRISPR-Cas systems enables the generation of an immunological memory to defend against invading viruses. This process is driven by foreign DNA spacer (termed protospacer) selection and integration mediated by Cas1-Cas2 protein. Recently, different states of Cas1-Cas2, in its free form and in complex with protospacer DNAs, were solved by X-ray crystallography. In this paper, molecular dynamics (MD) simulations are employed to study crystal structures of one free and two protospacer-bound Cas1-Cas2 complexes. The simulated results indicate that the protospacer binding markedly increases the system stability, in particular when the protospacer containing the PAM-complementary sequence. The hydrogen bond and binding free energy calculations explain that PAM recognition introduces more specific interactions to increase the cleavage activity of Cas1. By using principal component analysis (PCA) and intramolecular angle calculation, this study observes two dominant slow motions associated with the binding of Ca1-Cas2 to the protospacer and potential target DNAs respectively. The comparison of DNA structural deformation further implies a cooperative conformational change of Cas1-Cas2 and protospacer for the target DNA capture. We propose that this cooperativity is the intrinsic requirement of the CRISPR integration complex formation. This study provides some new insights into the understanding of CRISPR-Cas adaptation.
