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.

There is no one solvent that can dissolve every type of solute. Some substances that readily dissolve in a certain solvent might be insoluble in a different solvent. A simple way to predict which substances dissolve in which solvent is the phrase "like dissolves like". This means that polar substances, such as salt and sugar, dissolve in a polar substance like water. In contrast, non-polar substances are more soluble in non-polar solvents such as carbon tetrachloride. This selective solubility...

Standard Enthalpy of Formation

Enthalpy changes are typically tabulated for reactions in which both the reactants and products are at the same conditions. A standard state is a commonly accepted set of conditions used as a reference point for the determination of properties under other different conditions. For chemists, the IUPAC standard state refers to materials under a pressure of 1 bar and solutions at 1 M and does not specify a temperature. Many thermochemical tables list values with a standard state of 1 atm. Because...

A clean, polished tip provides a suitable glass surface for close contact with the cell membrane. This contact is essential because the seal must minimize unwanted electrical leakage around the pipette opening. Maintaining a well-prepared tip therefore improves electrical isolation and supports more precise measurements of membrane currents during electrophysiological recording.
Gentle suction draws the membrane toward the glass tip, increasing the closeness of the membrane-pipette interface. As contact improves, leakage around the recording site decreases and the electrical separation between the pipette interior and surrounding solution becomes stronger. The resulting high-resistance interface is important for resolving ionic currents with greater precision.
The seal creates a low-leakage interface that can support several recording approaches, including whole-cell, single-channel, and membrane-patch measurements. These configurations provide different levels of access to membrane electrical activity. Selecting among them allows investigators to examine overall cellular currents, activity through individual channels, or properties of an isolated membrane patch.
The procedure begins with a clean, polished glass micropipette and careful positioning of its tip against the cell membrane. Gentle suction then draws the membrane into close contact with the glass. When the interface becomes sufficiently tight, the resulting seal provides the electrical isolation needed to continue with whole-cell, single-channel, or membrane-patch recording.
Researchers use this technique when they need precise information about ionic currents or membrane electrical activity. It is particularly relevant to studies of ion-channel function, membrane excitability, and synaptic signaling. The approach also permits examination of how drugs or genetic changes affect cellular electrophysiology by comparing electrical responses under different experimental conditions.
Recordings obtained through the sealed interface can reveal ionic currents and activity associated with cell membranes or membrane patches. Depending on the selected recording configuration, investigators can examine whole-cell behavior, single-channel activity, or patch-level responses. These measurements help connect membrane electrical properties with signaling processes and experimental changes such as drug exposure or genetic modification.
