RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Main Methods:

Utilizing DNA multi-way junctions attached to DNA carriers for distinct current blockade levels in a nanopore.
Implementing quaternary encoding to increase data density compared to binary systems.
Employing toehold-mediated strand displacement reactions for precise DNA nanostructure manipulation.

Main Results:

Successfully encoded and encrypted a 2D grayscale image into 16 DNA carriers using quaternary barcodes.
Demonstrated simultaneous measurement and accurate recovery of the image data.
Achieved increased storage capacity and programmability without proteins or enzymes.

Conclusions:

A pure DNA storage system on a nanopore platform was realized, offering enhanced capacity and programmability.
