Ab initio modelling of photoinduced electron dynamics in nanostructures
… improved by decoration with metal nanoparticles (MNPs) due to a plasmonic enhancement effect. While such an effect has been demonstrated experimentally, it is hard to show theoretically from an ab initio point of view due to the computational demand of such calculations: the state-of- the-art …

CHEMICAL AND KINETIC STUDIES OF BACTERIAL TRANSPORT AND CHEMORECEPTOR PROTEINS
… probe 2-chloromercuri-4-nitrophenol (MNP) at a single site, cysteine residue 64. The addition of L-arabinose to MNP-modified L-arabinose-binding protein causes an increase in the nitrophenol pK to approximately 8.0 and a blue shift in the wavelength of maximum absorbance of the …

Optical Properties of Individual Nano-Sized Gold Particle Pairs
… and exploits the optical properties of pairs of MNPs. Pairs of MNPs offer two further parameters not existent at single MNPs, which both affect the local optical fields in their vicinity: the distance between them, and their relative orientation with respect to the polarisation of the excitation …

Removal of refractory contaminants from mature landfill leachate utilizing fungi and evaluation of lignocellulosic enzymatic activity
… (LiP), and manganese-peroxidase (MnP) activities of 250, 8, and 11 U/L from Penicillium sp. and 165, 19, and 27 U/L from T. chioneus. Penicillium sp. was also utilized in a continuous pack bed bioreactor operated at 48, 72, 96, and 120 h hydraulic retention time (HRT). Bioreactor …

Targeted magnetic nanoparticles for remote manipulation of protein aggregation
Local heat delivered by magnetic nanoparticles (MNPs) selectively attached to their target proteins can be used to manipulate and break up toxic or obstructive aggregates. We applied this magnetic hyperthermia treatment to the amyloid beta (A[beta]) peptide, which unnaturally folds and …

Investigating the spatiotemporal dynamics of mononuclear phagocytes in solid tumours.
Mononuclear phagocytes (MNP), consisting of monocytes, macrophages and dendritic cells (DC), are major cell types of the innate immune system and their activation is required for an effective immune response, including the anti-cancer response. Tumour-associated macrophages (TAM) are a universal …

Investigating the role of kidney mononuclear phagocytes in immune complex-induced inflammation.
Resident mononuclear phagocytes (MNPs) play key roles in tissue homeostasis, defence against infection and repair. Although MNPs have been studied for more than 130 years, there have been significant advances in our understanding of their role, origin, maintenance and interactions in recent years, …
