    Summary
    This summary is machine-generated.

    This study introduces a new fluorescence decay analysis method (F/F deconvolution) that simplifies data processing by using a single exponential decay. This approach accurately determines decay lifetimes and pre-exponential factors, overcoming instrument response function errors.
