Laser Disruption

Laser disruption is a targeted technique that uses focused laser energy to damage, remove, or alter selected cells, tissues, or subcellular structures while preserving surrounding material. In developmental biology, a precisely directed beam can induce localized photothermal or photomechanical damage, allowing researchers to interrupt cell function, sever cellular connections, or remove defined tissue regions at specific developmental stages. The resulting changes reveal how cells communicate, migrate, generate forces, and contribute to tissue patterning and organ formation. Laser disruption also supports experiments on regeneration and morphogenesis by providing controlled perturbations that can be linked to subsequent cellular and organismal responses.

2025

Begin with a mouse model of glioblastoma, an invasive brain tumor.At the tumor periphery, the blood-brain barrier (BBB) remains intact, with endothelial cells forming tight junctions that regulate molecular entry.The mouse is fitted with a head-mounted optical fiber to deliver laser light.Administer a low-intensity infrared laser, which penetrates the skin and skull to reach the brain.The laser excites molecular oxygen in brain cells, generating reactive oxygen species (ROS).The resulting...

Quorum-quenching enzymes are anti-virulent and anti-bacterial options that can mitigate pathogenesis without risk of incurring resistance, by preventing the expression of virulence factors and genes associated with antibiotic resistance and biofilm formation. In this study, we report a method that demonstrates the efficacy of quorum-quenching enzymes in bacterial biofilm disruption.

A protocol to detect and automate mode locking in a pre-adjusted nonlinear polarization rotation fiber laser is presented. The detection of a sudden change in the output polarization state when mode locking occurs is used to command the alignment of an intra-cavity polarization controller in order to find mode-locking conditions.

Single Photon Emission Computed Tomography for Assessing Brain Function Disruption

A traumatic brain injury, or TBI, impairs blood flow to the impacted regions and disrupts the activity of dopaminergic neurons.To investigate TBI-associated disruptions, begin by intravenously injecting a lipophilic radioactive tracer into a patient.The tracer travels through the cerebral vessels and diffuses into cells of the cortical and subcortical brain tissue.Perform single photon emission computed tomography, or SPECT, to detect the tracer-emitted radiation. The resulting signal intensity...
