Engineering Magnetotactic Bacteria as Medical Microrobots

Advanced Materials, EarlyView.
Magnetotactic bacteria (MTB) are living microorganisms that produce magnetosomes for navigation using the Earth's geomagnetic field. Their built‐in magnetic components, along with their intrinsic and/or modified biological functions, make them one of the most promising platforms for making future living and programmable microrobots.

Multi‐Module Micro/Nanorobots for Biomedical and Environmental Remediation Applications

Advanced Intelligent Systems, EarlyView.
Multi‐module microrobots (MNRs) have overcome the limitations of single‐module systems by integrating components such as propeller, actuator, manipulator, and imaging modalities. They show promise in biomedical applications, such as targeted drug delivery and tissue repair, as well as in environmental remediation, including pollutant removal.

The Synapse as a Central Target for Neurodevelopmental Susceptibility to Pesticides

Toxics, 2016
The developmental period of the nervous system is carefully orchestrated and highly vulnerable to alterations. One crucial factor of a properly-functioning nervous system is the synapse, as synaptic signaling is critical for the formation and maturation ...

Tris(1,3-dichloro-2-propyl) phosphate disrupts dorsoventral patterning in zebrafish embryos. [PDF]

, 2017
Tris(1,3-dichloro-2-propyl) phosphate (TDCIPP) is a high-production volume organophosphate flame retardant widely used within the United States. Within zebrafish, initiation of TDCIPP exposure at 0.75 h post-fertilization (hpf) results in genome-wide ...

Quantitative Analysis of Fluorescent Sensor Arrays

Analysis &Sensing, EarlyView.
Fluorescent sensor arrays have great potential for the quantification of analytes in complex systems. Herein, statistical multivariate techniques and deep learning models to provide quantitative information from such arrays are reviewed. Fluorescent sensor arrays address the limitations of a single sensor by leveraging multiple sensing elements to ...
