The interface between polymer science and bioconjugate chemistry is home to an active group of scientists who seek to combine the best of both worlds: the chemical versatility of polymeric architectures with the biological function of naturally occurring molecules. In recent years, novel methodologies have been developed, both in the area of polymer science as in the field of bioconjugate chemistry, which have now opened up opportunities to construct conjugates with unprecedented level of control. This selected group of recent publications, from the macromolecules journals family – ACS Macro Letters, Biomacromolecules, and Macromolecules, along with Bioconjugate Chemistry as well as Chemical Reviews, offers evidence of this progress and serves as an example of how the advances of the last half-decade in polymer synthesis can be combined with the evolved sophistication of biological macromolecules to access new materials. We hope this collection of publications will provide insight into recent developments in the area while also providing inspiration to those seeking to develop the next generation of bioconjugates.

As brain-focused research initiatives are established around the world, Brazil shines as an example of South America’s rise in the field. Organizations such as the BRAIN Institute at the Federal University of Rio Grande do Norte, the Edmond and Lily Safra International Institute of Neuroscience of Natal (ELS-IINN), and the Brazilian Institute of Neuroscience and Neurotechnology (BRAINN), serve as examples of recently established institutions dedicated to promote the growth of the neuroscience community.
Since the isolation of graphene in 2004, work on atomically thin two-dimensional (2D) materials has progressed rapidly across a diversity of scientific and engineering subfields. The types of 2D materials available has been ever growing and now includes insulators, (e.g., hexagonal boron nitride), semiconductors (e.g., transition metal dichalcogenides, TMDs), and additional semi-metals (e.g., black phosphorus). From these new materials, a wide array of optical, mechanical, chemical and electric phenomena have been realized in 2D crystals produced using top-down exfoliation, or bottom-up synthesis (e.g., by chemical vapor deposition, CVD). As 2D material science has become a mature field in-and-of itself, several key advantages have emerged that can be leveraged for new experimentation and device creation. These advantages include the amenability of 2D materials toward top-down and bottom-up lithography methods; their pliability and ability to be mechanically strained to create new structure–property–function relationships; and their unique chemistry, with large surface areas that lead to properties that are highly environmentally dependent.
Robert G. Bergman is honored in this Organometallics Virtual Issue as the 2017 recipient of the Wolf Prize in Chemistry. In 1972, he discovered a transformation of ene-diynes later identified by others as a crucial DNA-cleaving reaction in several antibiotics that bind to nucleic acids. It was in the mid-1970s that Bergman’s research broadened to include organometallic chemistry, which led to contributions in areas such as the development and study of the reaction mechanisms of migratory insertion and oxidative addition reactions and the seminal work on alkane carbon-hydrogen bond activation that led to his receiving the Wolf Prize in Chemistry this year.
This Virtual Special Issue is devoted to papers from authors who made outstanding presentations at the 251st ACS National Meeting in San Diego, California. We asked session chairs and symposia organizers within divisions that align with I&EC Research’s subject areas to identify the best presentation from their session. These presenters were invited to submit a manuscript to be published in I&EC Research. Following rigorous peer review, each accepted paper is published with a note indicating that it was an invited contribution as a result of an outstanding presentation at the ACS San Diego meeting. The topics covered include synthesis of polymeric materials that offer sustainability advantages, electrochemical systems, CO2 capture, tissue engineering, nanomedicine, drug discovery, and fundamentals of catalysis that can find energy-related applications. I&EC Research is delighted to showcase these twenty papers and feature these authors. The invited speakers are indicated below by their name in bold.
Anyone who doubts that analytical chemistry is a vital discipline should be directed to this issue of the journal. We invited over 20 authors to review developments in instrumentation and applications in selected areas of chemical analysis. They describe stunning advances in a variety of methods and applications. Clearly, analytical tools are getting cheaper and more available as seen in reviews on paper microfluidics, 3-D printing, digital assays, and point of care diagnostics. Several reviews tackle the impact of nanoscale and novel materials as enabling technology for a variety of sensors and assays.
It is an exciting time for the burgeoning area of biomaterials immunology. In the past few years, a surprising amount of research activity has blossomed, in which investigators seek to engineer immunity for a wide range of therapeutic and biotechnological goals. One has only to attend a biomaterials or bioengineering conference or to glance at the papers being published in journals such as this one to realize that immune engineering, biomaterials immunology, and their related endeavors have become recently energized.
The success of achieving high efficiency solar cells with methyl ammonium lead halide perovskites has enabled the field to explore new lead-free perovskite materials. The challenges of operational stability of organic lead halide perovskites and the environmental concern of the heavy metal content have led to the design of new perovskite materials. This virtual issue focuses on the recent developments in the area of “lead-free” metal halide perovskites. The papers compiled in this issue highlight initial success in synthesizing new classes of perovskite materials. The low power conversion efficiency and stability of these new perovskite materials still pose major hurdles with respect to finding suitable replacements to the lead-based compounds. Concerted efforts are needed to overcome these barriers, to make lead-free perovskites a contender for photovoltaic applications.
In this special issue of Chemistry of Materials on the subject of Computational Design of Functional Materials, we have invited a spectrum of researchers, ranging from early career scientists to established experts in the field, to showcase the use of computational techniques and address a variety of problems in materials chemistry. The nature of the materials studied covers the gamut from 2D transition metal dichalcogenides to oxides to hybrid framework materials and clathrate compounds. The material functions followed also span the range from semiconducting properties to mechanical properties to radiation stability, magnetic materials, and materials for energy storage applications. A particularly pleasing and somewhat unanticipated aspect of this special issue is that so many of the contributions combine experimental inputs in ways that have allowed for theory/experimental materials co-development. The era of theory versus experiment has clearly transitioned to an era of theory and experiment.
DNA polymerases play a central role in maintaining the integrity of genetic information, as these molecular machines carry out numerous DNA transactions. DNA polymerases can also be harnessed for biotechnology applications related to toxicology, specifically in the detection of DNA damage. The CRT virtual issue collection highlights a variety of approaches and systems to understand the molecular details of how DNA polymerases interact with the results of toxicant exposure.

The issue will attempt to provide the broad range of current and anticipated applications of these materials in designing drug release systems, sensors, imaging materials, actuators, switchable catalysts, and devices. The interdisciplinary impact of stimuli-responsive hydrogels on chemistry, biology, physics, electronics, and materials science will be on display.
