Manganese Dioxide Nanozymes as Responsive Cytoprotective Shells for Individual Living Cell Encapsulation

Angewandte Chemie International Edition, Journal Year: 2017, Volume and Issue: 56(44), P. 13661 - 13665

Published: Sept. 8, 2017

Abstract A powerful individual living cell encapsulation strategy for long‐term cytoprotection and manipulation is reported. It uses manganese dioxide (MnO 2 ) nanozymes as intelligent shells. As expected, yeast cells can be directly coated with continuous MnO shells via bio‐friendly Mn‐based mineralization. Significantly, the durable nanozyme not only enhance cellular tolerance against severe physical stressors including dehydration lytic enzyme, but also enable survival of upon contact high levels toxic chemicals prolonged periods. More importantly, these encased after shell removal a facile biomolecule stimulus fully resume growth functions. This applicable to broad range

Carbon dots-fed Shewanella oneidensis MR-1 for bioelectricity enhancement

Nature Communications, Journal Year: 2020, Volume and Issue: 11(1)

Published: March 13, 2020

Abstract Bioelectricity generation, by Shewanella oneidensis ( S. ) MR-1, has become particularly alluring, thanks to its extraordinary prospects for energy production, pollution treatment, and biosynthesis. Attempts improve technological output modification of MR-1 remains complicated, expensive inefficient. Herein, we report on the augmentation with carbon dots (CDs). The CDs-fed cells show accelerated extracellular electron transfer metabolic rate, increased intracellular charge, higher adenosine triphosphate level, quicker substrate consumption more abundant secretion. Meanwhile, CDs promote cellular adhesion, electronegativity, biofilm formation. In bioelectrical systems increase maximum current value, 7.34 fold, power output, 6.46 fold. enhancement efficacy is found be strongly dependent surface charge CDs. This work demonstrates a simple, cost-effective efficient route bioelectricity generation holding promise in all relevant technologies.

Single cell electron collectors for highly efficient wiring-up electronic abiotic/biotic interfaces

Nature Communications, Journal Year: 2020, Volume and Issue: 11(1)

Published: Aug. 14, 2020

Abstract By electronically wiring-up living cells with abiotic conductive surfaces, bioelectrochemical systems (BES) harvest energy and synthesize electric-/solar-chemicals unmatched thermodynamic efficiency. However, the establishment of an efficient electronic interface between surfaces is hindered due to requirement extremely close contact high interfacial area, which quite challenging for cell material engineering. Herein, we propose a new concept single electron collector, in-situ built interconnected intact layer on cross individual membrane. The collector forms intimate cellular transfer machinery maximizes achieving record-high efficiency BES performance. Thus, this provides superior tool wire at single-cell level adds dimensions abiotic/biotic
