Published Workflows
Objective: Develop nanoparticle-based optical voltage sensors for non-genetic, single-particle membrane-potential sensing with high temporal and spatial resolution and targeted subcellular readout.
Why it works: The review describes a coupled materials-and-methods strategy in which sensing particles are engineered for field sensitivity, surface ligands are designed to improve localization and compartmentalization, and optical readout methods are tailored to the sensing mechanism. This combination is presented as necessary for translating nanosensors into practical membrane-potential measurements at targeted sites.

Stages
- 1.simulation-guided surface-ligand design(library_design)
The abstract states that biomaterial-based surface ligands are designed from theoretical simulations to support anisotropic facet-selective coating and effective compartmentalization.

The abstract explicitly states that a dedicated home-built fluorescence microscope is used to record spectrally resolved images for QCSE measurements at the single-particle level.
Selection: measure QCSE-induced spectral shifts with a dedicated spectrally resolved fluorescence microscope
- 4.cell and neuron membrane-potential response testing(confirmatory_validation)
The abstract reports clear photoluminescence intensity changes in self-spiking and patched HEK293 cells and cortical neurons after staining with hybrid nanobiomaterials.
Selection: look for photoluminescence intensity changes in response to membrane-potential changes after staining cells with hybrid nanobiomaterials
- 5.targeted subcellular recording at synapses and spines(secondary_characterization)
The abstract highlights nanodisk-based non-invasive membrane-potential recording from individual targeted sites such as synapses and spines, indicating a more demanding targeted-use stage.
Selection: demonstrate non-invasive membrane-potential recording from individual targeted sites
- 6.action-potential recording milestone(decision_gate)
The abstract explicitly states that both QCSE- and FRET-based voltage nanosensors still need to reach this milestone.
