The superior efficacy of aminopolycarboxylic acid conjugated lipid nanoparticles over standard liposomal is described by Juan Chen, Gang Zheng et al. in their Research Article (e202218218). EDTA–lipid based fluidize the cell membrane a detergent-like manner and improve delivery to 25-fold. This novel nanoparticle design feature can be deployed across accelerate cancer nanomedicine drug delivery.

Nanoparticles with widely varying physical properties and origins (spherical versus irregular, synthetic versus biological, organic versus inorganic, flexible versus rigid, small versus large) have been previously noted to translocate across the cell plasma membrane. We have employed atomic force microscopy to determine if the physical disruption of lipid membranes, formation of holes and/or th...

BACKGROUND The present study takes advantage of the beneficial effects of resveratrol as a neuroprotective compound. Resveratrol-loaded solid lipid nanoparticles were functionalized with apolipoprotein E which can be recognized by the LDL receptors overexpressed on the blood-brain barrier. RESULTS Transmission electron microscopy images revealed spherical nanoparticles, dynamic light scatteri...

Oral cancer (oral cavity and oropharynx) is a common and aggressive cancer that invades local tissue, can cause metastasis, and has a high mortality rate. Conventional treatment strategies, such as surgery and chemoradiotherapy, have improved over the past few decades; however, they remain far from optimal. Currently, cancer research is focused on improving cancer diagnosis and treatment method...

The nonspecific adsorption of charged nanoparticles onto single-component phospholipid bilayers bearing phosphocholine headgroups is shown, from fluorescence and calorimetry experiments, to cause surface reconstruction at the points where nanoparticles adsorb. Nanoparticles of negative charge induce local gelation in otherwise fluid bilayers; nanoparticles of positive charge induce otherwise ge...

Progesterone containing nanoparticles constituted of tristearin or tristearin in association with caprylic-capric triglyceride were produced in a lab scale by ultrasound homogenization and in a pilot scale by high pressure homogenization. A study was conducted to select the pressure to be used in order to obtain homogenously sized nanoparticles. The Dialysis method was performed to mimic subcut...

A series of isopropyl fatty esters having different chain length (C(13)-C(23)) were synthesized and formulated in lipid nanoparticles based on Precirol ATO to evaluate their effect on the physicochemical properties of these latter. Moreover, drug loading and skin permeation of Econazole nitrate, chosen as a lipophilic model drug, were evaluated as well. The obtained nanosystems, prepared by hig...

Absorption of electromagnetic irradiation results in significant heating of metallic nanoparticles, an effect which can be advantageously used in biomedical contexts. Also, metallic nanoparticles are presently finding widespread use as handles, contacts, or markers in nanometer scale systems, and for these purposes it is essential that the temperature increase associated with electromagnetic ir...

Coaxial flow injection and mixing of solvent antisolvent flows prevent contact the lipid solution with microchannel walls enable stable continuous precipitation monodisperse nanoparticles in order 150 nm below.

Maghemite (γ-Fe2O3) nanoparticles were obtained by coprecipitation of ferrous and ferric salts in an alkaline medium followed by oxidation; the nanoparticles were coated with poly(N,N-dimethylacrylamide) (PDMA) and characterized by transmission electron microscopy, attenuated total reflection (ATR) Fourier transform infrared (FTIR) spectroscopy, dynamic light scattering, thermogravimetric and e...
