Abstract
The active ingredients of natural herbs have been extracted to act on different targets in the body to exert multiple effects. However, traditional oral administration and intravenous injection of herbal medicines are also susceptible to many side effects. Transdermal drug delivery by microneedles can overcome the shortcomings of these traditional drug delivery systems. The active ingredients of natural herbs can be delivered to the dermis or the connective tissue layer by five types of microneedles: solid, hollow, coated, dissolving, and hydrogel. Subsequently, the herbal ingredients are delivered to different target points of the body through body circulation to exert their effects. In this study, we classified the microneedles that can deliver the active ingredients of natural herbs and summarized their advantages and disadvantages as well as their preparation methods and applications, to guide the development and clinical applications of other herbal transdermal microneedles.
期刊介绍:
Biointerphases emphasizes quantitative characterization of biomaterials and biological interfaces. As an interdisciplinary journal, a strong foundation of chemistry, physics, biology, engineering, theory, and/or modelling is incorporated into originated articles, reviews, and opinionated essays. In addition to regular submissions, the journal regularly features In Focus sections, targeted on specific topics and edited by experts in the field. Biointerphases is an international journal with excellence in scientific peer-review. Biointerphases is indexed in PubMed and the Science Citation Index (Clarivate Analytics). Accepted papers appear online immediately after proof processing and are uploaded to key citation sources daily. The journal is based on a mixed subscription and open-access model: Typically, authors can publish without any page charges but if the authors wish to publish open access, they can do so for a modest fee.
Topics include:
bio-surface modification
nano-bio interface
protein-surface interactions
cell-surface interactions
in vivo and in vitro systems
biofilms / biofouling
biosensors / biodiagnostics
bio on a chip
coatings
interface spectroscopy
biotribology / biorheology
molecular recognition
ambient diagnostic methods
interface modelling
adhesion phenomena.
