Martens S, Klein S, Barnes R, TrejoSanchez P, Roth C, Ibey B
AMB Express . 2020 Mar; 10(1):55. PMID: 32189137
Cell suspensions of Escherichia coli and Lactobacillus acidophilus were exposed to 600-ns pulsed electric fields (nsPEFs) at varying amplitudes (Low-13.5, Mid-18.5 or High-23.5 kV cm) and pulse numbers (0 (sham),...

Beier H, Roth C, Bixler J, Sedelnikova A, Ibey B
Biophys J . 2018 Dec; 116(1):120-126. PMID: 30579565
Direct observation of rapid membrane potential changes is critical to understand how complex neurological systems function. This knowledge is especially important when stimulation is achieved through an external stimulus meant...

Valdez C, Barnes Jr R, Roth C, Moen E, Ibey B
Bioelectromagnetics . 2018 Jul; 39(6):441-450. PMID: 29984850
Nanosecond electric pulse (nsEP) exposure generates an array of physiological effects. The extent of these effects is impacted by whether the nsEP is a unipolar (UP) or bipolar (BP) exposure....

Martens S, Roth C, Ibey B
Bioelectromagnetics . 2018 Jul; 39(6):491-499. PMID: 29984845
Cell-circuit models have suggested that nanosecond pulsed electric fields (nsPEFs) can disrupt intracellular membranes including endoplasmic reticulum (ER), mitochondria, and/or nucleus thereby inducing intrinsic apoptotic pathways. Therefore, we hypothesized that...

Valdez C, Barnes Jr R, Roth C, Moen E, Throckmorton G, Ibey B
Sci Rep . 2017 Nov; 7(1):16372. PMID: 29180756
A bipolar (BP) nanosecond electric pulse (nsEP) exposure generates reduced calcium influx compared to a unipolar (UP) nsEP. This attenuated physiological response from a BP nsEP exposure is termed "bipolar...

Roth C, Glickman R, Martens S, Echchgadda I, Beier H, Barnes Jr R, et al.
Biochem Biophys Rep . 2017 Sep; 9:302-309. PMID: 28956017
Background: Exposure of cells to very short (<1 µs) electric pulses in the megavolt/meter range have been shown to cause a multitude of effects, both physical and molecular in nature....

Barnes R, Roth C, Beier H, Noojin G, Valdez C, Bixler J, et al.
Opt Express . 2017 Apr; 25(6):6621-6643. PMID: 28381008
Electric-field induced physical phenomena, such as thermal, mechanical and electrochemical dynamics, may be the driving mechanism behind bioeffects observed in mammalian cells during exposure to nanosecond-duration electric pulses (nsEP) in-vitro....

Tolstykh G, Tarango M, Roth C, Ibey B
Biochim Biophys Acta Biomembr . 2017 Jan; 1859(3):438-445. PMID: 28064021
Previously, it was demonstrated that nanometer-sized pores (nanopores) are formed in outer cellular membranes after exposure to nanosecond electric pulses (nsEPs). We reported that plasma membrane nanoporation affects phospholipids of...

Maswadi S, Ibey B, Roth C, Tsyboulski D, Beier H, Glickman R, et al.
Photoacoustics . 2016 Oct; 4(3):91-101. PMID: 27761408
Optoacoustic (OA) microscopy using an all-optical system based on the probe beam deflection technique (PBDT) for detection of laser-induced acoustic signals was investigated as an alternative to conventional piezoelectric transducers....

Roth C, Glickman R, Tolstykh G, Estlack L, Moen E, Echchgadda I, et al.
PLoS One . 2016 May; 11(5):e0154555. PMID: 27135944
Nanosecond electrical pulse (nsEP) exposure activates signaling pathways, produces oxidative stress, stimulates hormone secretion, causes cell swelling and induces apoptotic and necrotic death. The underlying biophysical connection(s) between these diverse...
