PCRlle

PCRlle is a term used in speculative and educational discussions to describe an integrated approach that augments traditional polymerase chain reaction (PCR) with real-time, spatially resolved detection inside microfluidic environments.

In the PCRlle concept, PCR is performed within a microfluidic chamber. Reporter probes or fluorescent dyes monitor amplification cycles, potentially enabling simultaneous data on where within a chip the product accumulates and how rapidly. Variants of the idea differ on whether detection is real-time imaging, end-point readout with localization, or both. The concept often envisages multiplexed channels or wells on a single chip, allowing parallel amplification with localized readouts.

Proposed benefits include higher throughput, reduced reagent consumption, and richer data on amplification dynamics, which could support diagnostics, batch analysis, single-cell workflows, and educational demonstrations.

Status and reception: The term is not part of a standard PCR methodology. It appears mainly in speculative discussions and teaching examples rather than in established protocols. Practical realization would require advances in signal multiplexing, chip fabrication, and data analysis, as well as careful validation of sensitivity and specificity.
