A graphene oxide/nickel/platinumnanoparticle micromotor(MM)-basedfluorescent aptassay is proposed to determine interleukin-6 (IL-6)in serum samples from low-birth-weight infants (gestational age ofless than 32 weeks and birthweight below 1000 g) with sepsis suspicion.In this kind of patients, IL-6 has demonstrated good sensitivity andspecificity for the diagnosis of sepsis, both for early and late onsetsepsis. The gene discussed is IL6; the disease is Sepsis.
