Strategies to improve micelle stability for drug delivery

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6201237/
    Compared with other drug delivery strategies, micelles have two unmatched advantages. The first is their relatively small size. The hydrodynamic sizes of a micelle is usually less than 50 nm [ 23 ].Author: Yang Lu, Ershuai Zhang, Jianhai Yang, Zhiqiang Cao

    The major obstacle for nanocarrier drug delivery is its clearance by reticuloendothelial system due to the size-induced antigenicity [46]. 12.6.1 Micelles as a Theranostic Carrier Micelles are polymeric colloidal particles with a size range of 5–100 nm and used as carriers for …

The Role of Micelle Size in Tumor Accumulation ...

    https://pubs.acs.org/doi/10.1021/acsnano.5b02017
    The as-prepared micelles had exactly the same chemical structures and similar physical properties except for size, which provided an ideal platform for a systematic investigation of the size effects in cancer drug delivery. We found that the micelle’s blood circulation time and tumor accumulation increased with the increase in their diameters, with optimal diameter range of 100 to 160 nm.Author: Jinqiang Wang, Weiwei Mao, Lye Lin Lock, Jianbin Tang, Meihua Sui, Weilin Sun, Honggang Cui, Dong Xu...

    In drug delivery, yield, given as a percent, is a reflection of the amount of drug delivered per amount encapsulated. How can micelle stability be improved? Micelles can have limited stability in vitro and in vivo stability due to the dynamic nature of their self-assembly into drug delivery systems; this instability can lead to premature drug ...

    Dec 12, 2019 · I have some experiences about hybrid nanomaterials for drug delivery, a year ago. At that time, I was curious that how can our body remove the …

Nanomicellar formulations for sustained drug delivery ...

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2902878/
    While plain PLGA micro particles released more than 50% of the drug in 1 day, optimal micelle formulations encapsulating PLGA particles released less than 30% of the drug at the end of 60 days. Figure 1 shows several types of micelles including regular micelles, reverse micelles and uni-molecular micelles used for drug delivery. Regular micelles are self-assemblies of amphiphilic copolymers in an aqueous medium while reverse micelles …Author: Ruchit Trivedi, Uday B Kompella
