Abstract
Metals are essential for human health and play a crucial role in numerous biological processes and pathways. Gaining a deeper insight into these biological events will facilitate novel strategies for disease prevention, early detection, and personalized treatment. In recent years, there has been significant progress in the development of metal-detection based techniques from single cell metallome and proteome profiling to multiplex imaging, which greatly enhance our comprehension of the intricate roles played by metals in complex biological systems. This perspective summarizes the recent progress in advanced metal-detection based techniques and highlights successful applications in elucidating the roles of metals in biology and medicine. Technologies including machine learning that couple with single-cell analysis such as mass cytometry and their application in metallobiology, cancer biology and immunology are also emphasized. Finally, we provide insights into future prospects and challenges involved in metal-detection based techniques, with the aim of inspiring further methodological advancements and applications that are accessible to chemists, biologists, and clinicians.

Abstract
![]()
Barcoding and pooling cells for processing as a composite
sample
are critical to minimize technical variability in multiplex technologies.
Fluorescent cell barcoding has been established as a standard method
for multiplexing in flow cytometry analysis. In parallel, mass-tag
barcoding is routinely used to label cells for mass cytometry. Barcode
reagents currently used label intracellular proteins in fixed and
permeabilized cells and, therefore, are not suitable for studies with
live cells in long-term culture prior to analysis. In this study,
we report the development of fluorescent palladium-based hybrid-tag
nanotrackers to barcode live cells for flow and mass cytometry dual-modal
readout. We describe the preparation, physicochemical characterization,
efficiency of cell internalization, and durability of these nanotrackers
in live cells cultured over time. In addition, we demonstrate their
compatibility with standardized cytometry reagents and protocols.
Finally, we validated these nanotrackers for drug response assays
during a long-term coculture experiment with two barcoded cell lines.
This method represents a new and widely applicable advance for fluorescent
and mass-tag barcoding that is independent of protein expression levels
and can be used to label cells before long-term drug studies.
