Sensitive detection systems for infectious agents in xenotransplantation*

open access: yesXenotransplantation, EarlyView., 2020
Abstract Xenotransplantation of pig cells, tissues, or organs may be associated with transmission of porcine microorganisms, first of all of viruses, to the transplant recipient, potentially inducing a disease (zoonosis). I would like to define detection systems as the complex of sample generation, sample preparation, sample origin, time of sampling ...

Ordered assembly of Cas12a for better performance of CRISPR/Cas system with application to the diagnosis of dental caries

open access: yesInterdisciplinary Medicine, EarlyView.
Here, we present a tetrahedral DNA framework (TDF)‐mediated Cas12a ordered assembly strategy. TDFs arrange CRISPR/Cas12a into ordered structures controllably, enhancing catalytic efficiency through localized Cas12a hotspots while maintaining spatial intervals to facilitate substrate diffusion.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

open access: yesPest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

Ultrasensitive MicroRNA Detection Combining Reduced Graphene Oxide Electrolyte‐Gated Transistors and Machine Learning

open access: yesSmall, EarlyView.
We developed an ultrasensitive and highly selective biosensor by integrating bio‐functionalized reduced graphene oxide (rGO) electrolyte‐gated transistors (EGTs) and machine learning (ML) to detect miRNAs (miR‐34a, miR‐34b, and miR‐34c) associated with cancer and neurological disorders.

Programmable Assembly of Higher‐Order DNA Nanostructures from Microbial ssDNA Staple Libraries

open access: yesSmall, EarlyView.
A phage‐free, microbial platform produces programmable circular ssDNA libraries that are enzymatically converted into DNA origami staple pools. Rolling‐circle replication generates sequence‐complex ssDNA with >99% fidelity, enabling assembly of DNA tiles and tubules and supporting nanostructure formation even in crude cellular lysates.

Cooperative Regulation of Defect‐Mediated Molecular Recognition With Single‐Walled Carbon Nanotubes

open access: yesSmall, EarlyView.
Defect‐mediated sensing in SWCNTs arises from the cooperative interplay of defect characteristics, density, heterogeneity, analyte properties, corona composition, and environment. Understanding these interconnected variables enables tunable fluorescence modulation, selective molecular recognition, ratiometric sensing, and sensitive detection in complex
