Introduction
The use of laser-polarized Xenon-129 exponential ($^{129}$Xe) as a novel contrast agent for MRI has been shown to be effective for functional (1,2) and structural imaging the brain (3) and other organs(4). It was approved by the FDA in December 2022. $^{129}$Xe-based imaging could transform our methods of mapping grey and white matter,(5) perfusion,(3) by...
Screening for breast cancer and disease is a routine and common practice among woman. Early detection of cancerous tumours has been shown to greatly reduce mortality. Commonly screening is performed using two-dimensional ultrasound, or mammographic imaging. A smaller dense breast is difficult to image on a mammogram system, and is more likely to be ultrasonically probed. Moreover, standard 2D...
The purpose of this poster is to show and discuss aspects of the construction and calibration of a new optical tweezers as well as an FCS setup. Optical tweezers use electromagnetic gradient forces together with radiation pressure to trap microscopic particles within a focused laser beam, and move them as required, making the tool suitable for applications in biological physics at microscopic...
Our goal is to develop a nano-biosensor using surface-enhanced Raman spectroscopy (SERS) to analyze and measure hemoglobin (Hb) levels, even at low concentrations, with good accuracy and reproducibility. This will facilitate fast and real-time differentiation of Hb disorders, such as sickle cell anemia, without using any labels or fluorophores.
To enhance the sensitivity of the Raman...
