A Brief Review of Graphene-Based Biosensors Developed for Rapid Detection of COVID-19 Biomarkers
The prevalence of mutated species of COVID-19 antigens has provided a strong impetus for identifying a cost-effective, rapid and facile strategy for identifying the viral loads in public places.

Coding capacity of complementary DNA strands [PDF]
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 ...

Mechanical separation of the complementary strands of DNA [PDF]
We describe the mechanical separation of the two complementary strands of a single molecule of bacteriophage λ DNA. The 3′ and 5′ extremities on one end of the molecule are pulled progressively apart, and this leads to the opening of the double helix. The typical forces along the opening are in the range of 10–15 pN. The separation force signal is

Complementary DNA Libraries and Neurological Disease [PDF]
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.

Background Bivalent thrombin‐binding aptamers (TBAs) have great potential for the treatment of thrombosis because they exhibit high anticoagulant activity, and their complementary single‐stranded DNA (ssDNA) sequences work as an antidote.

Towards New Liquid Crystal Phases of DNA mesogens [PDF]
Short, partially complementary, single-stranded (ss)DNA strands can form nanostructures with a wide variety of shapes and mechanical properties. It is well known that semiflexible, linear dsDNA can undergo an isotropic to nematic (IN) phase transition and that sufficiently bent structures can form a biaxial nematic phase.

Base Orientation of Second DNA in RecA·DNA Filaments. Analysis by combination of linear dichroism and small angle neutron scattering in flow-oriented solution [PDF]
To gain insight into the mechanism of pairing two complementary DNA strands by the RecA protein, we have determined the nucleobase orientation of the first and the second bound DNA strands in the RecA·DNA filament by combined measurements of linear ...

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