Nanostructured Lipid Carriers

At present, nanotechnology is widely utilized in drug delivery, facilitating both passive and active targeting through various administration routes. Solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) are the two primary types of lipid-based nanoparticles. Muller developed the NLCs in 1999-2000. NLCs come in three different forms:

Pathological Mechanism‐Inspired Biomimetic Nano‐Senotherapy for Reversing Experimental Atherosclerosis in ApoE−/− Mice

Advanced Science, EarlyView.
The biomimetic self‐assembly nanomedicine reversing atherosclerosis via senotherapy strategy. ABSTRACT The greatest challenge in atherosclerosis (AS) management lies in achieving lesion reversal, not merely slowing progression. Senescent cell accumulation—driven by continuous generation and apoptotic resistance—perpetuates plaque pathology and ...

Natural lipids in nanostructured lipid carriers and its cytotoxicity

Journal of Physics: Conference Series, 2017
Nanostructured lipid carriers (NLCs) are active carrier systems which modulate the sustained release of actives and protect unstable compounds against degradation. NLCs can also protect skin from sun light, due to its particulates nature, which gives them intrinsic scattering properties.

Membrane Fusion‐Mediated Cytosolic Delivery of Threose Nucleic Acids via Homotypic Nanoparticles Overcomes Drug Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study introduces a biomimetic “nanofusion” platform that integrates the biostability of threose nucleic acids (TNA) with homotypic cell‐membrane cloaking to combat drug‐resistant TNBC. By leveraging a non‐canonical membrane‐fusion pathway for direct cytosolic delivery, the platform bypasses endosomal sequestration. To achieve potent AKT2 silencing
