Inorganic Nanomaterials Meet the Immune System: An Intricate Balance
Advanced Healthcare Materials, EarlyView.Metal nanomaterials influence the immune responses, such as cytokine production and T‐cell activity. Unintended immune modulation can have significant consequences while its fine‐tuning may transform the oncology care. Within this review, a critical analysis is offered regarding the nano/immune‐interaction and suggests the future research directions to

Synthetic Routes to N-9 Alkylated 8-Oxoguanines; Weak Inhibitors of the Human DNA Glycosylase OGG1
Molecules, 2015 The human 8-oxoguanine DNA glycosylase OGG1 is involved in base excision repair (BER), one of several DNA repair mechanisms that may counteract the effects of chemo- and radiation therapy for the treatment of cancer. We envisage that potent inhibitors of

A Bio‐Inspired Perspective on Materials Sustainability
Advanced Materials, EarlyView.This perspective discusses natural materials as inspiration for sustainable engineering designs and the processing of materials. First, circularity, longevity, parsimony, and activity are presented as essential material paradigms. The perspective then uses many examples of natural and technical materials to introduce principles such as oligo ...

Long range correlations in DNA : scaling properties and charge transfer efficiency [PDF]
Phys. Rev. Lett. 91, 228101 (2003), 2003 We address the relation between long range correlations and charge transfer efficiency in aperiodic artificial or genomic DNA sequences. Coherent charge transfer through the HOMO states of the guanine nucleotide is studied using the transmission approach, and focus is made on how the sequence-dependent backscattering profile can be inferred from ...
