Aptamers coupled to nanoparticles in the diagnosis and treatment of microbial infections

There are nanoparticles with remarkable antibacterial characteristics and aptamers able to recognize specific pathogenic bacteria with high affinity and specificity. The combination of both systems has been used to design rapid bacterial detection methods with excellent detection limits. Likewise, the synergism between aptamers and nanoparticles have allowed to optimize the antimicrobial activity of antibiotics and other nanostructures providing them with activity bacterium-specific, turning into attractive and promising tools to fight against bacteria resistant to multiple antimicrobials.
