Stable Nanopores in Graphene

This technology consists of a method to fabricate a truly 2 dimensional porous surface using graphene with stabilized pore diameters less than a few nanometers. The nanopores are inert and stable for extended periods of time (several months) and under extreme conditions. The resulting membrane can be used in water purification, chemical separation, sensing, DNA sequencing, and other applications.

Mice Expressing Homozygous Human SCN5A (the Canonical Cardiac Sodium Channel) for the Study of Long QT Syndrome

Transgenic mice homozygous for the human cardiac sodium channel SCN5A gene (human-SCN5A H/H mice), on a C57 and 129sv background. These mice can be used to study function of the post-depolarization sodium current and gender-dependent long QT-related arrhythmias.

Novel Antimicrobial Peptide Isolated From Hydrothermal Vent-Dwelling Archaea

A new broad-spectrum antimicrobial enzyme for industrial and biopharmaceutical applications is undergoing characterization by Dr. Seth Bordenstein's laboratory at Vanderbilt University. It is expected to have unique therapeutic properties such as thermostability and tolerance of acidic environments.

Immortalized mouse epididymal epithelial cell lines

These cell lines are useful for studying the regulation of tissue-specific gene expression, and may also be used to identify epididymal-specific transcription factors involved in expression of specific proteins in the epididymis.

KCC2b Heterozygous Mice

KCC2b (Slc12a5) global knockout heterozygous mice on a C57BL/6J background. The Slc12a5 gene has alternative promoters which produce isoforms starting with exon 1a (5-10% total expression) and exon 1b (90-95% expression). As we targeted exon 1b, the mouse in not a global KO of KCC2 but a hypomorphic mouse, still expressing 5-10% protein. It is a global KCC2b KO mouse. Heterozygous animals develop spontaneous seizures in cages. This increases with age. Their brain is hyperexcitable. Homozygous animals die between P17 due to repeated tonic-cloning seizures.

Tools for targeting and assessing force generation in kinesins

Kinesins are motor proteins in eukaryotic cells powered by ATP hydrolysis. These proteins are involved in various cellular functions including cell division. In particular, Kinesin-5 (also known as KIF11 and Eg5) is essential to forming the microtubule spindle structure in mitosis; therefore, this protein is a potential target for chemotherapeutics. Chimeric kinesin proteins, comprising one or more regions from at least two kinesin proteins, are valuable tools to study the molecular mechanism of kinesin function as well as to identify agents that affect kinesin motor function.

COX2 Probes for Multimodal Imaging

Inventors at Vanderbilt University have developed a novel chemical design and synthesis process for azulene-based COX2 contrast agents which can be used for molecular imaging, via a variety of imaging techniques. These COX2 probes can be utilized for numerous applications, including imaging cancers and inflammation caused by arthritis and cardiovascular diseases. The process for developing these COX2 contrast agents has been significantly improved through a convergent synthesis process which reduces the required steps to establish the COX2 precursors.

Methods for Quick and Safe Deep Access into Mammalian Anatomy

This technology uses a novel continuum robot that provides a steerable channel to enable safe surgical access to the anatomy of a patient. This robotic device has a wide range of clinical application and is a significant advance from the rigid tools currently used in minimally invasive procedures.

Pulsed Infrared Light for the Inhibition of Central Nervous System Neurons

Vanderbilt researchers have developed a novel method for contactless simulation of the central nervous system. This technique involves the use of infrared neural stimulation (INS) to evoke the observable action potentials from neurons of the central nervous system. While infrared neural stimulation of the peripheral nervous system was accomplished almost a decade ago, this is the first technique for infrared stimulation of the central nervous system.

Grasping Applicator for Surgical Positioning (GRASP)

A team of Vanderbilt engineers and surgeons has developed a novel bone and tissue graft placement device, primarily for use in the nasal and skull base cavities. The device uses a unique grasping technique to provide control and finesse in the placement of such grafts in addition to combining the roles of multiple instruments into a single device. The clinical purpose of this tool is to provide surgeons with an instrument that can grasp, place, and manipulate rigid and non-rigid graft materials in a controlled manner for skull base reconstruction; such control is very desirable in order to recreate a sound bony barrier that separates the intracranial and extracranial spaces.

Low Cost Dexterous Wrists for Surgical Intervention

This invention presents a robotic wrist and gripper that operate with three independent degrees of freedom (yaw, pitch and roll) for increased dexterity in minimally invasive surgical procedures. This is the smallest robotic wrist of its kind, and due to its size and unparalleled dexterity, this wrist enables complex surgical maneuvers for minimally invasive procedures in highly confined spaces. Examples of surgical areas benefiting from use of this wrist include natural orifice surgery, single port access surgery, and minimally invasive surgery. In particular, the proposed wrist allows for very high precision roll about the longitudinal axis of the gripper while overcoming problems of run-out motion typically encountered in existing wrists. Thus this wrist is particularly suitable for extreme precision maneuvers for micro-surgery in confined spaces.

Algorithms for Contact Detection and Contact Localization in Continuum Robots

This technology enhances the capabilities of continuum robots by not only detecting contact during movement but also estimating the position of the contact during the movements executed by the robot. An algorithmic feedback loop can then constrain the movement of the robot to avoid damage to its robot arm, damage to another robot arm or damage to surrounding structure. Applications for this technology include enhanced safe telemanipulation for multi-arm continuum robots in surgery, micro-assembly in confined spaces, and exploration in unknown environments.
