Single-cell analysis has clearly established itself in biology and biomedical fields as an invaluable tool that allows one to comprehensively understand the relationship between cells, including their types, states, transitions, trajectories, and spatial position. Scientific methods such as fluorescence labeling…

Fluorogenic hybridization probes allow the detection and localization of specific mRNA molecules in living cells without the need for genetic engineering. However, with the fluorescence properties of currently available oligonucleotide probes, detection in live cells is difficult when the mRNA target is expressed at…

The Single-probe is a multifunctional device that can be coupled to mass spectrometry (MS) for molecular analysis of microscale samples, such as single cells, tissue slices, and multicellular spheroids, under ambient conditions. In Single-probe single cell MS (SCMS) studies, this technique leverages direct sampling and…

Single-cell mass spectrometry (SCMS) has emerged as a powerful tool for analyzing metabolites in individual cells, including live cells. However, cell metabolites have rapid turnover rate, whereas maintaining metabolites’ profiles of live cells during sample transport, storage, or extended measurements can be…

Recent progress in top-down mass spectrometry analysis of progressively larger nucleic acids has enabled in-depth characterization of intact, modified RNA molecules. Development of methods for desalting and MS/MS fragmentation allows rapid acquisition of high-quality top-down MS/MS spectra of nucleic acids up to 100…

Programmable droplets, artificial liquid-like condensates of nucleic acids, are intelligent out-of-equilibrium systems that allow the critical aspects of their biological counterparts to be harnessed programmably, such as molecular sensing and phase-state change. While DNA has been central to the previous efforts, less…

Large-scale de novo nucleic acid synthesis is a powerful tool enabling researchers to better understand and engineer biological systems. Fields ranging from genomics to nucleic acid therapeutics to synthetic biology make use of high-throughput experimental approaches requiring access to large pools or libraries of DNA…

Oligonucleotides offer a powerful class of new therapeutic modalities, which requires the support of robust and sensitive analytical methods. The primary structure of RNA-based therapeutic drugs is considered a critical quality attribute by regulatory agencies, and must be empirically confirmed to ensure quality…

In the last decade, there has been a shift in research, clinical development, and commercial activity to exploit the many roles of RNA in physiology for use in medicine. With the rapid success in the development of lipid-RNA nanoparticles for mRNA vaccines against COVID-19 and with several approved RNA-based drugs, RNA…
