The surface charge of trypanosomatids [PDF]

Anais da Academia Brasileira de Ciências, 2002
The surface charge of trypanosomatids was evaluated by means of the binding of cationic particles, as visualized by electron microscopy and by direct measurements of the electrophoretic mobility of cells.

Charged nanorods at heterogeneously charged surfaces [PDF]

The Journal of Chemical Physics, 2018
We study the spatial and orientational distribution of charged nanorods (rodlike counterions) as well as the effective interaction mediated by them between two plane-parallel surfaces that carry fixed (quenched) heterogeneous charge distributions. The nanorods are assumed to have an internal charge distribution, specified by a multivalent monopolar ...

Interaction between heterogeneously charged surfaces: Surface patches and charge modulation [PDF]

Physical Review E, 2013
When solid surfaces are immersed in aqueous solutions, some of their charges can dissociate and leave behind charge patches on the surface. Although the charges are distributed heterogeneously on the surface, most of the theoretical models treat them as homogeneous.

Biosensing with Surface Charge Modulated Graphene Field-Effect Transistors Beyond Nonlinear Electrolytic Screening [PDF]

, 2023
In field-effect transistor (FET) biosensors, charge screening in electrolyte solutions limits sensitivity, thereby restricting the applicability of FET sensors.

Decay of Electric Charge on Corona Charged Polyethylene [PDF]

, 2007
In this paper, the surface potential decay of corona-charged low density polyethylene (LDPE) films has been investigated. It has been found that for the same sample thickness the faster decay occurs in the sample with a higher charging voltage.

Surface Charge Mapping with a Nanopipette [PDF]

Journal of the American Chemical Society, 2014
Nanopipettes are emerging as simple but powerful tools for probing chemistry at the nanoscale. In this contribution the use of nanopipettes for simultaneous surface charge mapping and topographical imaging is demonstrated, using a scanning ion conductance microscopy (SICM) format.

Simulating Surface Charge Dynamics [PDF]

IEEE Transactions on Dielectrics and Electrical Insulation, 2021
Surface charge dynamics can play an important role in electric field distributions in both AC and DC insulation systems. In this paper the theory behind surface charge dynamics is introduced with a particular focus on the calculation of surface divergence; an operator which is used to determine movement of charge constrained to a surface.

Buried Charged Surface in Proteins [PDF]

Structure, 2000
The traditional picture of charged amino acids in globular proteins is that they are almost exclusively on the outside exposed to the solvent. Buried charges, when they do occur, are assumed to play an essential role in catalysis and ligand binding, or in stabilizing structure as, for instance, helix caps.By analyzing the amount and distribution of ...

Response of Osteoblasts on Amine-Based Nanocoatings Correlates with the Amino Group Density

Molecules, 2023
Increased life expectancy in industrialized countries is causing an increased incidence of osteoporosis and the need for bioactive bone implants. The integration of implants can be improved physically, but mainly by chemical modifications of the material
