Effects of the surface charge of polyamidoamine dendrimers on cellular exocytosis and the exocytosis mechanism in multidrug-resistant breast cancer cells

open access: yesJournal of Nanobiotechnology, 2021
Background Polyamidoamine (PAMAM) dendrimer applications have extended from tumor cells to multidrug-resistant tumor cells. However, their transportation in multidrug-resistant tumor cells remains unclear.

Manipulation of clusteroluminescence in carbonyl‐based aliphatic polymers

open access: yesAggregate, Volume 3, Issue 6, December 2022., 2022
Six nonconjugated carbonyl‐based aliphatic polymers with different heteroatoms and steric hindrances are synthesized and demonstrated with clusteroluminescence (CL). The results suggest that the additional heteroatoms will weaken the CL, but introducing the rigidification and crystallization effects can effectively improve the CL efficiency.

PAMAM dendrimers for the delivery of the antibacterial Triclosan [PDF]

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2008
Many oral care products incorporate an antibacterial compound to prevent the formation of dental plaque which predisposes teeth to dental caries or periodontal disease. Triclosan (TCN) is a commonly used antiplaque agent in toothpastes. Strategies to increase the delivery efficiency of antibacterials using formulation aids such as polyamidoamine (PAMAM)

Sensitive Detection of Dengue Virus Type 2 E-Proteins Signals Using Self-Assembled Monolayers/Reduced Graphene Oxide-PAMAM Dendrimer Thin Film-SPR Optical Sensor

open access: yesScientific Reports, 2020
In this work, sensitive detection of dengue virus type 2 E-proteins (DENV-2 E-proteins) was performed in the range of 0.08 pM to 0.5 pM. The successful DENV detection at very low concentration is a matter of concern for targeting the early detection ...
