DNA Fingerprinting
through researching the evolution of dna fingerprinting technology, it is concluded that its effects on society are of great importance. this iqp provides a basic background of how dna profiling is done and the correct methods for obtaining, transporting, and storing dna forensic samples. several landmark court cases are discussed showing a progression of acceptance of dna fingerprinting in the legal system. the purpose, ethics, and privacy rights associated with dna databases are also described, followed by the authors' conclusions about the influential effects this technology has on society

Nanoparticle Neuromodulation: A Perfusion Delivery System for the Study of the Interaction between Quantum Dots and Hippocampal Neurons
The current standards for whole-brain in vivo imaging cannot provide the resolution and neuron stimulation needed to study neuronal plasticity. Current in vivo studies of neuronal dynamics are limited to animal models, due to the deleterious effects of fluorophores. Nanoparticle quantum dots (QDs) are a promising alternative to traditional fluorophores. QDs have properties that can elicit electrical activity in neurons. Scientists at the University of Nova Gorica are studying this interaction. We designed a perfusion system to deliver drugs and QDs to neuron cultures. Using this device, and calcium imaging techniques, we demonstrated that the mechanism of interaction between carboxyl-coated QDs and hippocampal neurons is localized to the synapse, producing synchronous electrical activity
