Hyperchaotic color image encryption using eight-base DNA complementary rules and extended Zigzag transform. [PDF]

open access: yesPLoS ONE
As an efficient technique to protect image content from unauthorized access, image encryption has been a hot spot in recent studies. Among various schemes of image encryption, those that utilize hyperchaotic systems and deoxyribonucleicacid (DNA ...

The Application of Electrodeposited Poly(Propylene imine) Dendrimer as an Immobilisation Layer in a Simple Electrochemical DNA Biosensor

open access: yesInternational Journal of Electrochemical Science, 2011
We describe the application of poly(propylene imine) dendrimer in the preparation of a simple DNA biosensor. Generation one PPI was electrodeposited via cyclic voltammetry on glassy carbon electrode using a potential range of -100 to 1100 mV for 10 ...

Experimental validation of determinants of UV sensitivity using synthetic DNA

open access: yesJournal of Photochemistry and Photobiology, 2022
Treatment with ultraviolet (UV) light has been shown to be effective for disinfection of pathogens. For pathogenic risk management, it would be effective to estimate the UV sensitivity of unknown pathogenic microorganisms from their nucleotide sequences.

Coding capacity of complementary DNA strands [PDF]

open access: yesNucleic Acids Research, 1981
A Fortran computer algorithm has been used to analyze the nucleotide sequence of several structural genes. The analysis performed on both coding and complementary DNA strands shows that whereas open reading frames shorter than 100 codons are randomly distributed on both DNA strands, open reading frames longer than 100 codons ("virtual genes") are ...

Electrochemical Detection of Single Nucleotide Polymorphism in Short DNA Sequences Related To Cattle Fatty Acid Binding Protein 4 Gene

open access: yesInternational Journal of Electrochemical Science, 2012
Electrochemical nucleic acid biosensor for detection of single nucleotide polymorphism (SNP) in Fatty acid binding protein 4 (FABP4) has been developed by immobilization of single stranded thiolated probe DNA (ss-DNA-SH) onto gold surfaces (ss-DNA-SH/Au)

Complementary DNA Libraries and Neurological Disease [PDF]

open access: yesArchives of Neurology, 1998
The DNA in our cell nuclei contains all the information necessary to direct our biological functions. The gene is 1 unit of such information that usually specifies the expression of 1 protein product. A detailed knowledge of each gene will enable us to understand disease at the molecular level.

A highly sensitive electrochemical genosensor based on Co-porphyrin-labelled DNA [PDF]

open access: yes, 2014
We report the use of Co-porphyrins as electrochemical tags for a highly sensitive and selective genosensor. An avian influenza virus-based DNA sequence characteristic of H5N1 was detected at femtomolar levels from competing non-complementary sequences ...

Clerocidin selectively modifies the gyrase-DNA gate to induce irreversible and reversible DNA damage [PDF]

open access: yes, 2008
Clerocidin (CL), a microbial diterpenoid, reacts with DNA via its epoxide group and stimulates DNA cleavage by type II DNA topoisomerases. The molecular basis of CL action is poorly understood.

The Enhanced Sensitivity of a Porous Silicon Microcavity Biosensor Based on an Angular Spectrum Using CdSe/ZnS Quantum Dots

open access: yesSensors, 2019
To improve the detection sensitivity of porous silicon microcavity biosensors, CdSe/ZnS quantum dots are used to label complementary DNA molecules for the refractive index amplification and angular spectrum method for detection.
