The only major supermarket with a higher minimum spend before it offers free home delivery is Ocado, which charges between £2.99 and £6.99 for orders of between £40 and £75. At Sainsbury’s, the fee is £7 unless shoppers meet a minimum spend of £40 and at Asd...
Ocado delivery is overpriced they were charging £9.99 for Christmas delivery and had a minimum £90 basket, lots of things out of stock and charge for more expensive substitutes. Smart pass also expensive. Asda is shit and overcharged me £60 which took ages to return Sainsbury's was ...
They are a rip off check your receipt they will double it online don't order anything online they will scam you and if you cancel within 2 minutes they will charge you for cancelation fee bad company to deal with! Written November 19, 2024 This review is the subjective opinion of a...
However, on checking the bill, found we had been charged £3.50 for delivery and another 20 Pence because they had used a bag, Used to be that you ordered over a certain amount and delivery was free. Their menu shows no indication of these hidden charges ,and when we ord...
The positive charge of K allows it to stabilize anionic nucleic acids. The ability of poly- lysine NPs to condense DNA and efficiently transduce cells was demonstrated as early as 1996 [65]. Other polymers have been developed for use in PNPs, such as poly-lactic acid (PLA), poly-cryano...
Each sample was diluted to 0.2 wt % and vortexed for 5 min before conducting the experiments to decrease the viscosity and facilitate charge measurements. A Brookhaven BI-ZR3 Zeta Potential Analyzer (Brookhaven, Upton, NY, USA) with a 660 nm wavelength laser was used to determine the zeta ...
In addition, for these systems, higher radical scavenging activity was Molecules 2022, 27, 921 9 of 24 a "new" generation of liposomes, in which long-circulating liposomes are obtained by modulating lipid composition, size, and the charge of the vesicle. Particularly, liposomes with sizes ...
Modulation of surface charge, particle size and morphological properties of chitosan-tpp nanoparticles intended for gene delivery. Colloids Surf. B Biointerfaces 2005, 44, 65–73. [CrossRef] [PubMed] 14. Yata, V.K.; Ghosh, S.S. Investigating structure and fluorescence properties of green ...
The ζ potential was measured to reveal the surface charge variation of the micelles at different pH values. Figure 4C showed that the absolute value of the ζ potential decreased when the pH was changed from 7.4 to 5.5, whereas the HA–His micelles remained negatively charged because of the ...
Indeed, when EPO concentration was 67%, the change of the IPEC charge from negative to positive values, as estimated by the zeta potential, allows the dimethylamino groups of EPO to interact by ionic bonds with the negatively charged ionized groups of sialic acid at the terminus of mucin ...
