The spatial organization of the cell depends upon intracellular trafficking cargos hauled along microtubules and actin filaments by molecular motor proteins kinesin, dynein, myosin. Although much is known about how single motors function, there significant evidence that in vivo are carried multiple motors. While some aspects function have received attention, cargo itself —and on cargo—affects transport has not been considered. To address this, we developed a three-dimensional Monte Carlo...
We report on the fabrication and characterization of color-encoded chitosan hydrogels for rapid, sensitive specific detection bacterial enzymes as well selective a set tested bacteria through characteristic enzyme reactions. These patterned sensor are functionalized with three different colorimetric substrates affording multiplexed differentiation α-glucosidase, β-galactosidase β-glucuronidase. The limits an observation time 60 min using conventional microplate reader correspond to...
This work reports on a new approach to rapidly and selectively detect discriminate enzymes of pathogenic from those nonpathogenic bacteria using patterned autonomously reporting hydrogel transparent support, in which the selectivity has been encoded by pattern shape enable facile detection color change at one single wavelength. In particular, enzyme-responsive chitosan layers that report presence β-glucuronidase (β-Gus) β-galactosidase (β-Gal), produced nonvirulent Escherichia coli K12...
Here, we report a new pentafluoropropanamido rhodamine fluorescent probe (ACS-HNE) that allows for the selective detection of neutrophil elastase (NE). ACS-HNE displayed high sensitivity, with low limit (<5.3 nM), and excellent selectivity toward over other relevant biological analytes enzymes. The comparatively poor solubility cell permeability neat was improved by creating an ACS-HNE-albumin complex; this approach allowed improvements in situ visualization activity RAW 264.7 cells relative...
Herein, we demonstrate a combined fluorescent probe/shape-encoded hydrogel strategy for the fast, sensitive, and selective detection of bacterial species via their characteristic enzymes. A poly(vinyl alcohol) (PVA) loaded with probe N,N'-(3-oxo-3H-spiro[isobenzofuran-1,9'-xanthene]-3',6'-diyl)bis(2,2,3,3,3-pentafluoropropanamide) (ACS-HNE) was designed elastase, an enzyme produced by Pseudomonas aeruginosa. Likewise, chitosan-derived 4-methylumbelliferyl-α-d-glucopyranoside (MUD) entrapment...
In this work, patterned β‐GUS sensing chitosan hydrogels functionalized with three different colorimetric substrates were fabricated for the multiplexed detection of enzyme β‐glucuronidase (β‐GUS), which is secreted by >98% all known Escherichia coli ( E. ) strains. The immobilization fluorogenic and chromogenic in specified areas allows a spatially resolved readout corresponding signal. apparent initial rate induced cleavage reporter moieties films substrate 4‐nitrophenyl‐β‐D‐glucuronide...
Constructing hybrid heterostructures of transition-metal dichalcogenides is an effective strategy to enhance their electrochemical performance and stability as anode materials in lithium-ion batteries. In this work, a facile situ was developed engineer lattice-mismatched MoS2–ZnS together with C into hierarchical nanostructures. The three-dimensional architecture constructed using few-layer MoS2 nanosheets the building block, ZnS coexisted among mesoporous structure. By synergy effect...
We perform Monte Carlo type simulation studies of self-organization microtubules interacting with molecular motors. model as stiff polar rods equal length exhibiting anisotropic diffusion in the plane. The motors are implicitly introduced by specifying certain probabilistic collision rules resulting realignment rods. This approximation complicated microtubule-motor interaction a simple instant allows us to bypass ``computational bottlenecks'' associated details and dynamics reorientation...
A power system is employed to illustrate how we can apply singular perturbation theory decompose a full into two subsystems, slow and fast subsystems. Then, study the qualitative properties of their solutions finally obtain stability region an analytical expression approximate boundary operation point by numerical simulation computing local quadratic approximation one-dimensional stable manifold at saddle point. Furthermore, consider effects changing parameters on size region.
The fabrication, characterization and application of a nanoporous Silicon Rugate Filter (pSiRF) loaded with an enzymatically degradable polymer is reported as bare eye detection optical sensor for enzymes pathogenic bacteria, which devoid any dyes. nanopores pSiRF were filled poly(lactic acid) (PLA), which, upon enzymatic degradation, resulted in change the effective refractive index film, leading to readily discernible color sensor. shifts characteristic fringe patterns before after...
