Nowadays, more and more nanotechnology products and nanomaterials are being applied in our lives. Silver nanoparticles (SNPs) are used in infection prevention and treatment due to their antimicrobial activity. However, as a kind of nanomaterial, the toxicology of SNPs has not been completely studied. The mechanism of cytotoxicity of SNPs in vitro to mouse's(More)
We developed a microfluidic biochip to perform laser guidance on two cell types, chick embryonic forebrain neurons and spinal cord neurons. Observation of neurons under a high-magnification microscope, which we obtained from these two cell types, showed no difference in morphology. However, when flowing in the microfluidic channel and simultaneously being(More)
Because the nervous system is most vulnerable to toxicants during development, there is a crucial need for a highly sensitive developmental-neurotoxicity-test model to detect potential toxicants at low doses. We developed a lab-on-chip wherein single-neuron axonal pathfinding under geometric guidance was created using soft lithography and laser(More)
Various types of animal neurons were cultured on a microelectrode array (MEA) platform to form biosensors to detect potential environmental neurotoxins. For a large-scale screening tool, rodent MEA-based cortical-neuron biosensors would be very costly but chick forebrain neurons (FBNs) are abundant, cost-effective, and easy to dissect. However, chick FBNs(More)
Magnesium (Mg)-based biomaterials have shown great potential in clinical applications. However, the cytotoxic effects of excessive Mg(2+) and the corrosion products from Mg-based biomaterials, particularly their effects on neurons, have been little studied. Although viability tests are most commonly used, a functional evaluation is critically needed. Here,(More)
