Key procedures to optimize the sealing process and achieve real-time monitoring of the metal-to-glass seal (MTGS) structure are described in detail. The embedded fiber Bragg grating (FBG) sensor is designed to achieve online monitoring of temperature and high-level residual stress in the MTGS with simultaneous environmental pressure monitoring.

2026
A novel sealing protocol to produce water-tight silicone-based seals for membranes of Polydimethylsiloxane (PDMS) chip devices. Intended for labs setting-up chip models and small-scale chip platform development. We demonstrate the protocol using plastic and native tissue membranes. This procedure only requires PDMS, toluene, mold, membrane, and a vacuum chamber.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Convection-Enhanced Delivery of Antibodies into a Mouse Brain

This video demonstrates a convection-enhanced delivery (CED) technique for antibody delivery into the mouse brain. The skull of an anesthetized mouse is exposed, and a burr hole is created at the target area for antibody delivery. A step catheter containing antibodies is inserted at the target site, and via an infusion pump, a pressure gradient is created to deliver antibodies at a controlled rate.
FAQs
It promotes closer contact between the cell membrane and the recording electrode, which raises seal resistance at their interface. The tighter electrical barrier reduces ionic leakage and suppresses background electrical noise. As a result, the recorded signal more accurately reflects membrane potential, ion-channel activity, or whole-cell currents rather than unwanted current escaping around the electrode.
High seal resistance helps isolate the electrical activity of the cell from the surrounding solution and electrode interface. When forming a high-resistance gigaseal is difficult, a sealing enhancer can improve membrane contact and reduce leakage that would otherwise interfere with recordings. This supports cleaner signals and more dependable measurements of cellular electrical behavior.
Their main contribution is to reduce two related sources of poor data quality: ionic leakage through an imperfect electrode-membrane interface and background electrical noise. Improving the seal can make membrane potential, ion-channel activity, and whole-cell current measurements more stable. The benefit is especially relevant when the initial electrode-cell contact does not readily produce a high-resistance seal.
A sealing enhancer may be used either as a reagent or as a procedural aid during patch-clamp recording. Its role is to support closer electrode-membrane contact while the seal is being established, particularly when achieving a high-resistance gigaseal proves difficult. The immediate procedural objective is a less leaky, lower-noise interface suitable for stable electrical measurement.
Researchers may consider one when electrode contact with the cell membrane does not produce a sufficiently high-resistance seal or when leakage and background noise compromise recording quality. Improved sealing can help stabilize measurements and extend experiment duration. This makes the approach useful for experiments that require reliable observation of membrane potential, ion-channel activity, or whole-cell currents.
A better seal supports more reliable characterization of cellular excitability and membrane transport by improving the quality of electrical recordings. Depending on the patch-clamp configuration and measurement, researchers can obtain more stable information about membrane potential, ion-channel activity, or whole-cell currents. The improved interface also increases confidence that measured signals represent cellular behavior rather than recording-related leakage or noise.
