Optical tweezers use the momentum of photons to capture and manipulate particles in a noncontact way. Although related techniques have been widely used in biology and materials, research on viruses is still relatively limited. It is hard to optically trap viruses because trap stiffness is rather low and the size of viruses is too small. Here, we used an optical tweezers system coupled with a laser confocal fluorescence imaging system, which allows individual viruses to be imaged and trapped in real time and analyzed using multiple parameters in the culture medium. We show that a single virus tagged by quantum dots (QDs) can increase the real part of polarizability, further increasing gradient force and trap stiffness. With this method, we not only can trap and manipulate viruses in real time but also can analyze their interactions with other targets.

“…This allows the use of permittivity as a measure of membrane capacitance and, consequently, enables estimation of the quantity of microorganisms in a given solution containing cells such as erythrocytes, lymphocytes, and protoplasts [1,2]. Hence, dielectric spectroscopy is increasingly being utilized for quantifying a variety of microorganisms including Escherichia coli, yeasts, and plant viruses [3][4][5][6]. This approach facilitates the development of a non-destructive, label-free assays that can be used for direct assessment of a wide…”

Although traditionally used primarily for assessing the physical properties of solids, dielectric spectroscopy has found new utility in quantifying microorganisms in liquids. The lipid bilayer membranes of bacteria and viruses possess capacitive properties, and the electrical capacitance is directly proportional to the surface area of the membrane. This allows the use of permittivity as a measure of membrane capacitance and, consequently, enables estimation of the quantity of microorganisms in a given solution containing cells such as erythrocytes, lymphocytes, and protoplasts [1,2]. Hence, dielectric spectroscopy is increasingly being utilized for quantifying a variety of microorganisms including Escherichia coli, yeasts, and plant viruses [3][4][5][6].

We present a novel compact electric permittivity sensor that exploits Bleustein-Gulyaev (BG) waves propagating along the surface of shear-poled piezoelectrics. We formulate the dynamic nonlinear electromechanical partial differential equations of motion governing wave propagation under electromagnetically quasistatic conditions. The permittivity of the medium-under-test was found to influence the sensor eigenvalues, enabling the implementation of a frequency-shift permittivity sensor. Solution of the equations of motion demonstrates resonance of the first and third modes when excited using an IDT. We fabricated two sensor prototypes on shear-poled PZT4 and LiNbO3 substrates and used a Vector Network Analyzer to observe the shift in their fundamental natural frequency in the presence of various media-under-test. S11 measurements show deterministic and repeatable shifts in the resonant frequency of the first mode of the LiNbO3 sensor measured at △f1=3.51 MHz for ethanol and △f1=7.49 MHz for deionized water where the bare surface frequency was initially at f1=25.27 MHz.
