Abstract
While single-cell mass spectrometry can reveal cellular heterogeneity and the molecular mechanisms of intracellular biochemical reactions, its application is limited by the insufficient detection sensitivity resulting from matrix interference and sample dilution. Herein, we propose an intact living-cell electrolaunching ionization mass spectrometry (ILCEI-MS) method. A capillary emitter with a narrow-bore, constant-inner-diameter ensures that the entire living cell enters the MS ion-transfer tube. Inlet ionization improves sample utilization, and no solvent is required, preventing sample dilution and matrix interference. Based on these features, the detection sensitivity is greatly improved, and the average signal-to-noise (S/N) ratio is about 20 : 1 of single-cell peaks in the TIC of ILCEI-MS. A high detection throughput of 51 cells per min was achieved by ILCEI-MS for the single-cell metabolic profiling of multiple cell lines, and 368 cellular metabolites were identified. Further, more than 4000 primary single cells digested from the fresh multi-organ tissues of mice were detected by ILCEI-MS, demonstrating its applicability and reliability.

Abstract
Dopamine participates in many physiological and pathological processes. Dynamic monitoring of dopamine levels in the cytoplasm of a single living cell reflects not only the functional state of dopamine synthesis factors but also the processes of related neurodegenerative diseases. Due to the low content of cytoplasmic dopamine and the difficulty to keep cells alive during the operating process, the detection of cytoplasmic dopamine is still challenging. Herein, a solid-phase microextraction (SPME) technique integrated nanobiosensor was employed to trace and quantify dopamine concentration fluctuations in the cytoplasm of a single living cell. We designed a polypyrrole modified carbon fiber nanoprobe as a bifunctional nanoprobe that can extract cytoplasmic dopamine and then perform electrochemical detection. This bifunctional nanoprobe can detect 10 pmol/L extracted dopamine and detected a 60% decrease of the cytoplasmic dopamine concentration in a single living cell by K+ stimulation. This study allowed for the first time serially detecting cytoplasmic dopamine while keeping the target cell alive, which might yield a new method for research on dopamine neurotoxicity and the related drug action mechanisms for neurodegenerative disease.
