<p>Lipid-based nanoparticles (LBNs) are a new type of nanoparticulate drug delivery system, which have been gradually shown broad prospects in pulmonary drug delivery systems. However, the main disadvantage of these LBNs for inhalable drugs with limited lipophilicity is the low encapsulation capacity. Herein, this study anticipates establishing a technology platform to improve the loading capacity of low lipophilicity drugs in LBNs, for the therapy of lung diseases. A proof-of-concept was carried out using Beclomethasone dipropionate (BDP) as a model drug. BDP was conjugated with stearic acid (SA), a kind of the lipid matrix for LBN. The conjugate was characterized and the interactions between the conjugate and SA were investigated by molecular dynamics simulation. It is expected that the drug loading capacity of weak-lipophilic drugs in LBN can be increased by establishing the technology platform, and the application of LBNs in pulmonary delivery can be broadened.</p>

Dual Targeting

A dual-targeting drug delivery system (DTDDS) with magnetic targeting and active targeting was obtained to improve the targeting and drug-loading capacity of magnetic drug nanocarriers. An ultraviolet-visible spectrophotometer and flow cytometry were used to investigate the drug-loading and release capacity, cytotoxicity, and inhibition of tumor cell proliferation, separately. Results show that DTDDS has obvious magnetic characteristics, on which the modification amount of folic acid is 64.82 mg g-1. Doxorubicin was taken as a template drug to evaluate its drug-loading capacity, which was as high as 577.12 mg g-1. Good biocompatibility and low cytotoxicity of DTDDS were further confirmed. Moreover, DTDDS can target the folate receptor on the surface of HeLa cells and deliver doxorubicin into HeLa cells, thereby increasing the proliferation inhibition for cancer cells. Therefore, this new dual-targeting drug delivery system shows potential in significantly reducing the toxic side effects of chemotherapy and improving chemotherapy efficiency.

The Impact

Cellulose beads were successfully prepared from waste denim using a dissolution-regeneration approach with ionic liquids as the dissolving solvent. Cellulose beads with different morphologies were achieved by altering the dissolving and coagulating solvents. The morphological differences were quantified by N2 physisorption. The impact of morphology on the cellulose beads’ potential application was investigated in the context of drug loading and release. The results show that the fibrous morphology showed a better loading capacity than the globular analogue due to its higher surface area and pore volume.
