Plasmonic-Based Biosensor For The Early Diagnosis Of Prostate Cancer, Thakshila Liyanage, Bayan Alharbi, Linh Quan, Aurora Esquela-Kerscher, Gymama Slaughter Jan 2022

Plasmonic-Based Biosensor For The Early Diagnosis Of Prostate Cancer, Thakshila Liyanage, Bayan Alharbi, Linh Quan, Aurora Esquela-Kerscher, Gymama Slaughter

Bioelectrics Publications

A tapered optical fiber (TOF) plasmonic biosensor was fabricated and used for the sensitive detection of a panel of microRNAs (miRNAs) in human serum obtained from noncancer and prostate cancer (PCa) patients. Oncogenic and tumor suppressor miRNAs let7a, let-7c, miR-200b, miR-141, and miR-21 were tested as predictive cancer biomarkers since multianalyte detection minimizes false-positive and false-negative rates and establishes a strong foundation for early PCa diagnosis. The biosensing platform integrates metallic gold triangular nanoprisms (AuTNPs) laminated on the TOF to excite surface plasmon waves in the supporting metallic layer and enhance the evanescent mode of the fiber surface. …

Dosage control of reactive oxygen and nitrogen species (RONS) is critical to low-temperature plasma applications in cancer therapy. Production of RONS by atmospheric pressure, nonequilibrium plasmas in contact with liquid may be modulated via plasma conditions including plasma treatment time and pulse voltage and repetition frequency. In this study, a terephthalic acid-based probe was used to measure hydroxyl radicals [OHaq] in water exposed to plasma and to demonstrate that the OHag concentration increases linearly with treatment time. Fluorometric measurements of hydrogen peroxide concentration in plasma-activated water show a linear relationship between the H2O2 production …


Targeted And Controlled Anticancer Drug Delivery And Release With Magnetoelectric Nanoparticles, Alexandra Rodzinski Nov 2016

Targeted And Controlled Anticancer Drug Delivery And Release With Magnetoelectric Nanoparticles, Alexandra Rodzinski

FIU Electronic Theses and Dissertations

A major challenge of cancer treatment is successful discrimination of cancer cells from healthy cells. Nanotechnology offers multiple venues for efficient cancer targeting. Magnetoelectric nanoparticles (MENs) are a novel, multifaceted, physics-based cancer treatment platform that enables high specificity cancer targeting and externally controlled loaded drug release. The unique magnetoelectric coupling of MENs allows them to convert externally applied magnetic fields into intrinsic electric signals, which allows MENs to both be drawn magnetically towards the cancer site and to electrically interface with cancer cells. Once internalized, the MEN payload release can be externally triggered with a magnetic field. MENs uniquely allow …


Old Remedies In The Biotechnology Age: Moore V. Regents, Michelle J. Burke, Victoria M. Schmidt Jun 1992

Old Remedies In The Biotechnology Age: Moore V. Regents, Michelle J. Burke, Victoria M. Schmidt

RISK: Health, Safety & Environment (1990-2002)

The California Supreme Court, by excluding a potential remedy, has eliminated many concerns generated by a lower court decision resolving rights to the cell line derived from John Moore's spleen. Yet, the Supreme Court gave little attention to remedies that remain. The authors argue that a constructive trust, a remedy of considerable vintage and great flexibility, could be applied to achieve a just result in such circumstances without affecting the biotechnology world at large.
