This study was designed to evaluate whether nano-hydroxyapatite toothpastes with or without fluoride would be more advantageous than a fluoride toothpaste in the repair of eroded enamel in situ. Twenty-one subjects participated in this single-blind, randomized, cross-over design study with three 7-day treatment phases. In each phase, the subjects wearing a palatal appliance containing five sterilized

Nature-inspired slippery polymer thin film for ice-repellent applications Bioinspired, Biomimetic Nanobiomater. (IF 1.732) Pub Date : 2021-09-01 Vu Thi Hong Hanh,Mai Xuan Truong,Tu Quang Tan,Thanh-Binh Nguyen
In this study, the authors investigated the anti-icing performance of a hierarchical slippery polymer thin film that is inspired by structures of the lotus leaf and Nepenthes pitcher plant. The polymer solution was mixed with the lubricant at the appropriate concentration to achieve slippery properties. The dry etching method followed by the spin-coating process was used to generate a uniform polymer

Bioactivity-guided nanoparticle synthesis from Zingiber officinale and Mentha longifolia Bioinspired, Biomimetic Nanobiomater. (IF 1.732) Pub Date : 2021-09-01 Raja Adil Sarfraz,Rizwan Ashraf,Saira Bedi,Iqra Sardar
To date, various reports have exhibited the antidiabetic activity of plant extracts, but this activity could be improved through the conversion of plant bioactives into metal nanoparticles. Aqueous plant extracts were prepared from two plants, Zingiber officinale and Mentha longifolia. Silver nanoparticles from aqueous plant extracts were synthesized and characterized through spectroscopic techniques

Chitosan-based nanoparticles for controlled release of hydrophobic and hydrophilic drugs Bioinspired, Biomimetic Nanobiomater. (IF 1.732) Pub Date : 2021-09-01 Jing Zhao,Xiaoran Wang,Xingyue Deng,Kaiwen Liu
Nanoparticles encapsulating different kinds of therapeutic drugs are promising drug delivery systems for controlling release and targeting tumor cells. Chitosan nanoparticles made by polyelectrolyte complexation were designed as drug carriers using doxorubicin (DOX)/5-fluorouracil (5-FU) as hydrophobic/hydrophilic model drugs. The sizes of nanoparticles were 235 ± 13 and 177 ± 7 nm with narrow distributions

Facile fabrication of Luffa cylindrica-assisted 3D hydroxyapatite scaffolds Bioinspired, Biomimetic Nanobiomater. (IF 1.732) Pub Date : 2021-06-22 Bijayinee Mohapatra, Tapash R Rautray
The incidence of bone-related disorders is abruptly increasing worldwide, and the current therapies available are not sufficient to fulfill the growing demands of patients. Porous three-dimensional (3D) structures cast in combination with ceramics and polymers, with an intention to mimic native bone tissues, are gaining importance because of their better physicochemical and biological activities. The

Effects of kartogenin/PLGA nanoparticles on silk scaffold properties and stem cell fate Bioinspired, Biomimetic Nanobiomater. (IF 1.732) Pub Date : 2021-07-20 Maryam Rezvaninia, Fatemeh Bagheri, Nafiseh Baheiraei
Cartilage is an avascular and aneural connective tissue with poor self-healing capability. Recently, tissue engineering opens up new horizons for staving off or treating cartilage lesions. In this work, kartogenin (KGN), a small chondro-inductive molecule, was loaded into poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs), which in turn was embedded in a silk fibroin (SF) scaffold, to prepare
