Multiplexed DNA-Directed Patterning of Antibodies for Applications in Cell Subpopulation Analysis.
Article in ACS applied materials & interfaces, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Antibodies provide the functional biospecificity that has enabled the development of sensors, diagnostic tools, and assays in both laboratory and clinical settings. However, as multimarker screening becomes increasingly necessary due to the heterogeneity and complexity of human pathology, new methods must be developed that are capable of coordinating the precise assembly of multiple, distinct antibodies. To address this technological challenge, we engineered a bottom-up, high-throughput method in which DNA patterns, comprising unique 20-base pair oligonucleotides, are patterned onto a substrate using photolithography. These microfabricated surface patterns are programmed to hybridize with, and instruct the multiplexed assembly of, antibodies conjugated with the complementary DNA strands. We demonstrate that this simple, yet robust, approach preserves the antibody-binding functionality in two common applications: antibody-based cell capture and label-free surface marker screening. Using a simple proof-of-concept capture device, we achieved high purity separation of a breast cancer cell line, MCF-7, from a blood cell line, Jurkat, with capture purities of 77.4% and 96.6% when using antibodies specific for the respective cell types. We also show that antigen-antibody interactions slow cell trajectories in flow in the next-generation microfluidic node-pore sensing (NPS) device, enabling the differentiation of MCF-7 and Jurkat cells based on EpCAM surface-marker expression. Finally, we use a next-generation NPS device patterned with antibodies against E-cadherin, N-cadherin, and β-integrin-three markers that are associated with epithelial-mesenchymal transitions-to perform label-free surface marker screening of MCF10A, MCF-7, and Hs 578T breast epithelial cells. Our high-throughput, highly versatile technique enables rapid development of customized, antibody-based assays across a host of diverse diseases and research thrusts.
