However, the creation of practical graphene electronic sensors greatly depends on our ability to understand and maintain a low level of electronic noise, the fundamental reason limiting the sensor resolution. Conventionally, to reach the largest sensing response, graphene transistors are operated at the point of maximum transconductance, where 1/f noise is found to be unfavorably high and poses a major limitation in any attempt to further improve the device sensitivity. We show that operating a graphene transistor in an ambipolar mode near its neutrality point can markedly reduce the 1/f noise in graphene. Remarkably, our data reveal that this reduction in the electronic noise is achieved with uncompromised sensing response of the graphene chips and thus significantly improving the signal-to-noise ratio—compared to that of a conventionally operated graphene transistor for conductance measurement. As a proof-of-concept demonstration of the usage of the aforementioned new sensing scheme to a broader range of biochemical sensing applications, we selected an HIV-related DNA hybridization as the test bed and achieved detections at picomolar concentrations. 000838721 536__ $$0G:(DE-HGF)POF3-552$$a552 - Engineering Cell Function (POF3-552)$$cPOF3-552$$fPOF III$$x0 000838721 536__ $$0G:(DE-HGF)POF3-553$$a553 - Physical Basis of Diseases (POF3-553)$$cPOF3-553$$fPOF III$$x1 000838721 536__ $$0G:(DE-HGF)POF3-523$$a523 - Controlling Configuration-Based Phenomena (POF3-523)$$cPOF3-523$$fPOF III$$x2 000838721 588__ $$aDataset connected to CrossRef 000838721 7001_ $$00000-0001-9817-8680$$aFeng, Lingyan$$b1 000838721 7001_ $$0P:(DE-Juel1)128715$$aPanaitov, Gregory$$b2 000838721 7001_ $$0P:(DE-Juel1)159559$$aKireev, Dmitry$$b3 000838721 7001_ $$0P:(DE-Juel1)128707$$aMayer, Dirk$$b4 000838721 7001_ $$0P:(DE-Juel1)128713$$aOffenhäusser, Andreas$$b5 000838721 7001_ $$0P:(DE-Juel1)128697$$aKrause, Hans-Joachim$$b6 000838721 773__ $$0PERI:(DE-600)2810933-8$$a10.1126/sciadv.1701247$$gVol. 3, no. 10, p. e1701247 -$$n10$$pe1701247 -$$tScience advances$$v3$$x2375-2548$$y2017 000838721 8564_ $$uhttps://juser.fz-juelich.de/record/838721/files/e1701247.full.pdf$$yOpenAccess 000838721 8564_ $$uhttps://juser.fz-juelich.de/record/838721/files/e1701247.full.gif?subformat=icon$$xicon$$yOpenAccess 000838721 8564_ $$uhttps://juser.fz-juelich.de/record/838721/files/e1701247.full.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000838721 8564_ $$uhttps://juser.fz-juelich.de/record/838721/files/e1701247.full.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000838721 8564_ $$uhttps://juser.fz-juelich.de/record/838721/files/e1701247.full.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000838721 8564_ $$uhttps://juser.fz-juelich.de/record/838721/files/e1701247.full.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000838721 909CO $$ooai:juser.fz-juelich.de:838721$$pdnbdelivery$$pVDB$$pdriver$$popen_access$$popenaire 000838721 9101_ $$0I:(DE-588b)5008462-8$$60000-0002-1090-0411$$aForschungszentrum Jülich$$b0$$kFZJ 000838721 9101_ $$0I:(DE-588b)5008462-8$$60000-0001-9817-8680$$aForschungszentrum Jülich$$b1$$kFZJ 000838721 9101_ $$0I:(DE-HGF)0$$60000-0001-9817-8680$$a ICS-8$$b1 000838721 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)128715$$aForschungszentrum Jülich$$b2$$kFZJ 000838721 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)159559$$aForschungszentrum Jülich$$b3$$kFZJ 000838721 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)128707$$aForschungszentrum Jülich$$b4$$kFZJ 000838721 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)128713$$aForschungszentrum Jülich$$b5$$kFZJ 000838721 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)128697$$aForschungszentrum Jülich$$b6$$kFZJ 000838721 9131_ $$0G:(DE-HGF)POF3-552$$1G:(DE-HGF)POF3-550$$2G:(DE-HGF)POF3-500$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bKey Technologies$$lBioSoft – Fundamentals for future Technologies in the fields of Soft Matter and Life Sciences$$vEngineering Cell Function$$x0 000838721 9131_ $$0G:(DE-HGF)POF3-553$$1G:(DE-HGF)POF3-550$$2G:(DE-HGF)POF3-500$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bKey Technologies$$lBioSoft – Fundamentals for future Technologies in the fields of Soft Matter and Life Sciences$$vPhysical Basis of Diseases$$x1 000838721 9131_ $$0G:(DE-HGF)POF3-523$$1G:(DE-HGF)POF3-520$$2G:(DE-HGF)POF3-500$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bKey Technologies$$lFuture Information Technology - Fundamentals, Novel Concepts and Energy Efficiency (FIT)$$vControlling Configuration-Based Phenomena$$x2 000838721 9141_ $$y2017 000838721 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000838721 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal 000838721 915__ $$0LIC:(DE-HGF)CCBYNC4$$2HGFVOC$$aCreative Commons Attribution-NonCommercial CC BY-NC 4.0 000838721 915__ $$0StatID:(DE-HGF)0112$$2StatID$$aWoS$$bEmerging Sources Citation Index 000838721 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000838721 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000838721 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000838721 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000838721 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000838721 920__ $$lyes 000838721 9201_ $$0I:(DE-Juel1)ICS-8-20110106$$kICS-8$$lBioelektronik$$x0 000838721 9201_ $$0I:(DE-82)080009_20140620$$kJARA-FIT$$lJARA-FIT$$x1 000838721 9801_ $$aFullTexts 000838721 980__ $$ajournal 000838721 980__ $$aVDB 000838721 980__ $$aUNRESTRICTED 000838721 980__ $$aI:(DE-Juel1)ICS-8-20110106 000838721 980__ $$aI:(DE-82)080009_20140620 000838721 981__ $$aI:(DE-Juel1)IBI-3-20200312
