Tuning the Surface Charge of Self-Assembled Polydiacetylene Vesicles to Control Aggregation and Cell Binding

Biosensors, 2020
Polydiacetylene vesicles of various compositions were assembled using a two-part mixture of 10,12-pentacosadiynoic acid (PCDA) and ethylenedioxy-bis-ethylamine (EDEA)-labeled PCDA in order to control surface charge and stability within a desired pH range.

Measurement and visualization of cell membrane surface charge in fixed cultured cells related with cell morphology.

PLoS ONE, 2020
The diagnosis of patients with malignancies relies on the results of a clinical cytological examination. To enhance the diagnostic qualities of cytological examinations, it is important to have a detailed analysis of the cell's characteristics. There is,

Electrostatic Interaction with the Bacterial Cell Envelope Tunes the Lytic Activity of Two Novel Peptidoglycan Hydrolases

Microbiology Spectrum, 2022
Peptidoglycan (PG) hydrolases, due to their crucial role in the metabolism of the bacterial cell wall (CW), are increasingly being considered suitable targets for therapies, and a potent alternative to conventional antibiotics.

Positively charged nanocomplex modulates dendritic cell differentiation to enhance Th1 immune response

Materials Today Bio, 2022
Most existing vaccines use activators that polarize the immune response to T-helper (Th) 2 response for antibody production. Our positively charged chitosan (Cs)-based nanocomplex (CNC) drives the Th1 response through unknown mechanisms. As receptors for

The surface charge of trypanosomatids of the genus trypanosoma

Memorias do Instituto Oswaldo Cruz, 1990
Cell electrophoresis was used for determionation of the electrophoretic mobility (EPM) of epimastigo and trypamastigote forms of several isolates of Trypanosoma cruzi and some stocks of other members of the Schizotrypanum subgenus, such as T. dionisii, T.
