Hollow Pollen Shells to Enhance Drug Delivery

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3978527/
    Mar 14, 2014 · This morphology was regarded as being so applicable to drug delivery that artificial pollen particles have been produced using silica [1,2], calcium carbonate or calcium phosphate , and iron oxide , but these particles lack the elasticity of exines extracted from plant pollen and spores and are difficult to make free from defects. It is possible to attach drugs to the outside of complete particles, …Author: Alberto Diego-Taboada, Stephen T. Beckett, Stephen L. Atkin, Grahame Mackenzie

    Aug 08, 2018 · A new chemical process removes the allergenic material from pollen grains so that the empty shells can be used for drug delivery.

Big pharma backs pollen-based drug delivery

    https://www.in-pharmatechnologist.com/Article/2007/01/31/Big-pharma-backs-pollen-based-drug-delivery
    Jan 31, 2007 · The drug delivery system is based on the fact that some plant pollens and spores are able to cross the wall of the human gut, where they are then destroyed within the blood stream. Using pollen-based vehicles to transport drugs would harness this mechanism, so as the pollen is destroyed, the active ingredient encapsulated within is released.

    Microparticles with strong adhesion property was presented as efficacious drug delivery systems. Here, inspired by natural pollen, polymer microparticles with surface textures and homogeneous size were fabricated through evaporation-induced interfacial instability of microfluidic droplets templates.Author: Yuetong Wang, Yuetong Wang, Luoran Shang, Guopu Chen, Changmin Shao, Yuxiao Liu, Peihua Lu, Fei Rong...

Hollow Pollen Shells to Enhance Drug Delivery

    https://www.mdpi.com/1999-4923/6/1/80
    Pollen grain and spore shells are natural microcapsules designed to protect the genetic material of the plant from external damage. The shell is made up of two layers, the inner layer (intine), made largely of cellulose, and the outer layer (exine), composed mainly of sporopollenin.Author: Alberto Diego-Taboada, Stephen T. Beckett, Stephen L. Atkin, Grahame Mackenzie
