SAMDI-MS, which stands for self-assembled monolayers (SAMs) for matrix-assisted laser desorption ionization (MALDI) mass spectrometry (MS), is a powerful tool that has enabled the development of novel high-throughput screening and experimentation methods for decades. SAMDI-MS works by immobilizing analytes to functionalized SAMs prior to MS analysis and is capable of...
No two cells in a population are identical to each other. Cell populations are almost universally heterogeneous, with their heterogeneity or variability often underlying complex emergent behavior and phenotypes. Heterogeneity presents a challenge to the discovery, characterization, and control of multicellular systems. Heterogeneity exists across multiple scales, ranging from the...
Chimeric antigen receptor (CAR) T-cell therapies marry advances in cellular engineering with personalized medicine to provide patient-specific, targeted cancer treatments. Though current CAR T-cell therapies successfully target blood cell cancers, treating solid tumors has proven to be more challenging. Solid-tumor CAR designs must overcome several challenges, including tumor microenvironment barriers...
Biological experiments involving the manipulation and analysis of cells have always strived towards greater precision and resolution. Recent advances in micro and nanotechnology have improved the precision of manipulation and the resolution of analysis down to a single cell, thus opening new avenues of investigation. These advances have added a...
Current technologies capable of establishing bioresorbable orthopedic fixation devices and stents have broad utility for biomedical applications to improve constructive tissue remodeling. Recent studies and investigations on bioresorbable conductors, semiconductors, dielectrics, and polymer substrates offer a promising opportunity to propel the existing non-degradable bioelectronic devices to the promising bioresorbable electronics,...
Biological therapeutics have revolutionized the way we treat cancer due to their ability to target tumors discriminately, leaving healthy cells unaffected. However, our inability to tailor the structure of biologics may hamper their optimization for efficacy. This lack of programmability contributes to factors such as immunogenic responses, inability to penetrate...
A major distinction among different skeletal muscles in the human body is the number, size, and arrangement of its cells, referred to as a muscle’s architecture. Muscle architecture is indicative of a muscle’s ability to contract and produce force and, like muscle function, is plastic. While neuromuscular plasticity is the...
The Escherichia coli ribosome is a molecular machine capable of sequence-defined polymerization of -amino acids into proteins, a feat unmatched by any other current synthetic catalyst. It is complex in its structure, comprised of 3 RNA parts (the 5S, 16S, and 23S ribosomal RNAs) and 54 ribosomal proteins (r-proteins). Efforts...
By 2030, up to half of the world’s population is projected to suffer from water insecurity: a chronic scarcity of potable water due to rapidly warming temperatures, increased agricultural demand, and pollution. The health impacts of contaminated water are profound: hundreds of thousands of global deaths each year are ascribed...
While metabolic engineering can enable the sustainable bioproduction of new materials, efforts are often impeded by pathway bottlenecks. To mitigate the effects of toxic or reactive intermediates and resource competition resulting from heterologous pathway incorporation, bacterial microcompartments (MCPs) have recently been considered for engineered compartmentalization in bacterial host organisms. MCPs...
