Flocking ferromagnetic colloids.

Science advances

Kaiser A, Snezhko A, Aranson IS.
PMID: 28246633
Sci Adv. 2017 Feb 15;3(2):e1601469. doi: 10.1126/sciadv.1601469. eCollection 2017 Feb.

Assemblages of microscopic colloidal particles exhibit fascinating collective motion when energized by electric or magnetic fields. The behaviors range from coherent vortical motion to phase separation and dynamic self-assembly. Although colloidal systems are relatively simple, understanding their collective response,...

Sustainable magnet-responsive nanomaterials for the removal of arsenic from contaminated water.

In this study, chitosan and bio-based substances (BBS) obtained from composted biowaste were used as stabilizers for the synthesis of magnet-sensitive nanoparticles (NPs) via coprecipitation method. A pyrolysis treatment was carried out on both biopolymers at 550°C, and their...

Modeling bond correlations in denatured proteins and polypeptides.

Biopolymers

Betancourt MR.
PMID: 26850703
Biopolymers. 2016 Jun;105(6):312-323. doi: 10.1002/bip.22816.

Bond-orientational correlations for finite-length homopolypeptides and a selected group of denatured proteins are obtained by numerical simulations using a polypeptide model with a potential of mean force. These correlations characterize the stiffness of the polypeptide backbone and are generally...

Exopolysaccharides enriched in rare sugars: bacterial sources, production, and applications.

Frontiers in microbiology

Roca C, Alves VD, Freitas F, Reis MA.
PMID: 25914689
Front Microbiol. 2015 Apr 10;6:288. doi: 10.3389/fmicb.2015.00288. eCollection 2015.

Microbial extracellular polysaccharides (EPS), produced by a wide range of bacteria, are high molecular weight biopolymers, presenting an extreme diversity in terms of chemical structure and composition. They may be used in many applications, depending on their chemical and...

A review on polymeric hydrogel membranes for wound dressing applications: PVA-based hydrogel dressings.

Journal of advanced research

Kamoun EA, Kenawy ES, Chen X.

Iranian journal of pharmaceutical research : IJPR

Mahobia S, Bajpai J, Bajpai AK.
PMID: 28243266
Iran J Pharm Res. 2016;15(4):695-711.

The aim of the present work was to prepare and characterize biopolymer nanocarriers and evaluate their suitability in possible oral delivery of insulin. The egg albumin biopolymer was used to prepare nanoparticles which were further characterized by Fourier transformed...

Facile fabrication processes for hydrogel-based microfluidic devices made of natural biopolymers.

Biomicrofluidics

Yajima Y, Yamada M, Yamada E, Iwase M, Seki M.
PMID: 24803964
Biomicrofluidics. 2014 Apr 17;8(2):024115. doi: 10.1063/1.4871936. eCollection 2014 Mar.

We present facile strategies for the fabrication of two types of microfluidic devices made of hydrogels using the natural biopolymers, alginate, and gelatin as substrates. The processes presented include the molding-based preparation of hydrogel plates and their chemical bonding....

Exchange-Correlation Functional with Good Accuracy for Both Structural and Energetic Properties while Depending Only on the Density and Its Gradient.

Journal of chemical theory and computation

Peverati R, Truhlar DG.
PMID: 26588964
J Chem Theory Comput. 2012 Jul 10;8(7):2310-9. doi: 10.1021/ct3002656. Epub 2012 Jun 13.

The generalized gradient approximation (GGA) has been a workhorse exchange-correlation functional for electronic structure studies of extended systems (liquid-phase reactions, solids, heterogeneous and enzymatic catalysis, biopolymers) because its dependence on only the spin-labeled electron densities and their reduced gradients...

A liquid-crystalline hexagonal columnar phase in highly-dilute suspensions of imogolite nanotubes.

Nature communications

Paineau E, Krapf ME, Amara MS, Matskova NV, Dozov I, Rouzière S, Thill A, Launois P, Davidson P.
PMID: 26728415
Nat Commun. 2016 Jan 05;7:10271. doi: 10.1038/ncomms10271.

Liquid crystals have found wide applications in many fields ranging from detergents to information displays and they are also increasingly being used in the 'bottom-up' self-assembly approach of material nano-structuration. Moreover, liquid-crystalline organizations are frequently observed by biologists. Here...
