By Nathaniel Wand.

“We are on the verge of a post-antibiotic world. Multi-resistant strains of bacteria now pose a major threat to world health, as effective treatments run out. To diagnose a strain of MRSA currently takes 72 hours as the DNA code is sequenced: ACGTAGCTAGA...”

"The aim of my research is to develop an alternative approach, not by reading out letters but to scan DNA barcodes.

On the far right of the image is DNA which has been combed onto a surface. It has been modified at specific positions to effectively create a DNA ‘barcode’." 

Nathaniel Wand is a postgraduate reseacher at The Centre for Doctoral Training in Physical Sciences of Imaging in the Biomedical Sciences (PSIBS) .
