Silva C, Bernardes J, Loh W
Carbohydr Polym . 2023 Jan; 302:120354. PMID: 36604044
Nanocellulose is a well-known stabilizer for several colloidal dispersions, including emulsions and solid nanoparticles, replacing surfactants, polymers, and other additives, and therefore providing more minimalistic and eco-friendly formulations. However, could...

Aquino Queiros M, Loh W
J Phys Chem B . 2022 Jul; 126(28):5362-5373. PMID: 35819870
The mixture of two oppositely charged polyelectrolyte solutions results in complexation that may lead to an associative phase separation, forming a highly concentrated phase in both polyelectrolytes in equilibrium with...

Trindade S, Piculell L, Loh W
Langmuir . 2022 Feb; 38(9):2906-2918. PMID: 35189060
We used diblock poly(acrylic acid)--poly(2-dimethylamino ethyl methacrylate) (PAA--PDMAEMA) polyampholytes to prepare core-shell complexes with ionic surfactants. The dispersions have been characterized by means of small-angle X-ray scattering (SAXS), cryogenic transmission...

Villalva D, Franca C, Loh W
Colloids Surf B Biointerfaces . 2022 Feb; 212:112352. PMID: 35101824
Cubosomes are dispersions of bicontinuous surfactant phases that constitute an assertive option to carry and release drugs and biomolecules, offering high efficiency of entrapment and specificity towards biological targets. This...

ACS Appl Bio Mater . 2022 Jan; 2(5):1975-1986. PMID: 35030686
To shed light on novel sustainable materials with antimicrobial functionality, in this contribution, we describe the use of cationic nanocellulose to produce foams featuring antibacterial activity against the powerful human...

Ferreira G, Loh W, Topgaard D, Soderman O, Piculell L
Polymers (Basel) . 2021 Oct; 13(19). PMID: 34641081
Internally structured block copolymer-surfactant particles are formed when the complex salts of ionic-neutral block copolymers neutralized by surfactant counterions are dispersed in aqueous media. Here, we report the H NMR...

Aquino Queiros M, Loh W
Polymers (Basel) . 2021 Jul; 13(14). PMID: 34301019
In this work, we report the phase behavior of polyelectrolyte complex coacervates (PECs) of poly(acrylate) (PA) and poly(diallyldimethylammonium) (PDADMA) in the presence of inorganic salts. Titrations of the polyelectrolytes in...

Aquino Queiros M, Loh W
J Phys Chem B . 2021 Mar; 125(11):2968-2975. PMID: 33720730
We report here a systematic study on the phase behavior of dodecyltrimethylammonium-poly(acrylate) (CTAPA) complex salts upon addition of simple salts (NaBr and NaCl). Complex salts of poly(acrylate) of two molar...

Eur J Pharm Sci . 2021 Feb; 160:105748. PMID: 33567324
Glaucoma is a degenerative optic neuropathy characterized by increased intraocular pressure that if untreated can result in blindness. Ophthalmological drug therapy is a challenge of great clinical importance due to...

Langmuir . 2020 Dec; 36(49):15018-15029. PMID: 33275433
Understanding of the temperature-induced phase transition of poly(oligo(ethylene glycol) methyl ether methacrylate) (POEGMA) random copolymers with varied composition remains largely incomplete. Upon heating they can form either macroscopically phase-separated aggregates...
