Magnetic DNA random access memory with nanopore readouts and exponentially-scaled combinatorial addressing
Description
Nowadays, synthetic DNA can be used as a storage medium. Several experiments have been conducted, providing proof-of-concepts. The authors of [1] present a new decoding technique that works on the raw signals of the biological sequencer when retrieving stored data. This method was partially already presented in [2].
The student's task is to understand the working flow of DNA-based data storage. Further, one needs to understand the error-correction mechanisms and the specific overall experimental setup of [1]. The pros and cons of this scheme have to be evaluated and discussed.
