Nanomaterial bio-activation and macromolecules functionalization: The search for reliable protocols

Protein Expression and Purification
Ario de Marco

Abstract

The possibility of successfully applying nanomaterials such as biosensors or nanoparticles in diagnostics and therapy is critically dependent on the capacity to optimize their target recognition selectivity and their ability to be delivered minimizing off-side accumulation. Biological macromolecules possess the necessary specificity and for this reason have been often coupled to nanomaterials. However, such process is not straightforward because it often induces structural alterations of the involved macromolecules, in most of the cases proteins or antibodies the functions of which can be hampered when single amino acids are modified. Several strategies have been proposed to rationalize the methodology of macromolecule functionalization with reactive groups and tags that should improve the nanomaterial bio-activation in terms of final yields, process simplicity and reproducibility, and cost-efficiency. This review will describe the features of both chemical and enzymatic reactions exploited to activate polypeptide residues as well as some of the strategies suitable for preparing recombinant proteins fused to tags directly accessible for nanomaterial modification.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
