Figure 3From: Mass spectrometry based on a coupled Cooper-pair box and nanomechanical resonator system Plot of frequency shifts versus the number of DNA molecules landing on twodifferent masses of NRs. Other parameters used are ω n = 835 MHz, λ 0 = 0.01, Δ c = 0. Q = 5000, T 1 = 0.25 μ s,T 2 = 0.05 μ s, and Ω c = 3.Back to article page
