Abstract
Magnetic nanoparticles can be electrostatically assembledaroundspermcells toformbiohybridmicrorobots. Thesebiohybridmicrorobots possess sufficientmagneticmaterial to potentially allow for pulse-echo localization and wireless actuation.Alternatively,magnetic excitationof these nanoparticlescanbeusedfor localizationbasedonFaraday’s lawof inductionusingadetectioncoil.Here, we investigate the influenceof theelectrostaticattractionbetweenpositively chargednanoparticles andnegativelychargedspermcells on theactivationofthenanoparticlesduringnonlineardifferential magnetometryandwirelessmagneticactuation.Activationof clustersof freenanoparticlesandnanoparticlesboundto the bodyof spermcells is achievedbyacombinationof ahighfrequency alternating field and a pulsating static field. The nonlinear response inboth cases indicates that constraining thenanoparticles is likelytoyieldsignificantdecreases inthe magnetometrysensitivity.Whiletheattachmentofparticles to thecellsenableswirelessactuation(rollinglocomotion),therate of changeof themagnetizationof thenanoparticlesdecreases oneorderofmagnitudecomparedtofreenanoparticles.
