cord-296921-0trs364m	Shin, Minkyu	Flexible HIV-1 Biosensor Based on the Au/MoS(2) Nanoparticles/Au Nanolayer on the PET Substrate	2019-07-26		.txt	text/plain	5475	303	57	An electrochemical flexible biosensor composed of gold (Au), molybdenum disulfide nanoparticles (MoS(2) NPs), and Au (Au/MoS(2)/Au nanolayer) on the polyethylene terephthalate (PET) substrate is developed to detect envelope glycoprotein GP120 (gp120), the surface protein of HIV-1. The current increase of the Au/MoS 2 /Au nanolayer on the PET substrate compared to conventional bare gold electrode was due to the large surface area and the efficient electron transfer by MoS 2 NPs. Nanomaterials 2019, 9, x FOR PEER REVIEW 6 of 12 The reduction and oxidation peak currents of the Au/MoS 2 /Au nanolayer on the PET substrate derived from the redox generator were 1.13 mA and −1.17 mA, respectively, which were much higher than those peaks of the bare gold electrodes with 0.96 mA and −1.01 mA due to the large surface area and effective electron transfer of the synthesized MoS 2 NPs. The fabricated biosensor showed highly sensitive detection of gp120 with a detection limit of 0.066 pg/mL, which was more sensitive than previously reported electrochemical HIV biosensors.	./cache/cord-296921-0trs364m.txt	./txt/cord-296921-0trs364m.txt
