Lecture by

Daniel Simon

Docent of Organic Bioelectronics, Linköping University, Sweden

Title: “Panbio-electronics”

Time18:00
Place: Hall C, Chemical Center, Naturvetarvägen 14

Abstract

Recent decades have seen the rise of a range of tools and technologies for interfacing technological and biological systems. There has been a consistent focus on animal and mammalian applications, particularly relating to neuroscience, and organic electronics have emerged as an ideal component in these applications. However, we have recently shown that organic electronics can also be applied to augment plant systems, brining decades of anthropocentric R&D to the plant kingdom. In this talk, I will introduce our recent advances and results in animal-focused and plant-focused “panbio-electronics”.

Title: “The amyloid β peptide in Alzheimer´s disease: molecular interactions and structure conversions studied by chemical and biophysical methods ”

Time18:00
Place: Hall C, Chemical Center, Naturvetarvägen 14

Abstract

 

The amyloid β (Aβ) peptide consists of 39-43 residues and is the major component of the neuritic plaques in the brains of Alzheimer's disease (AD) patients. It is possible to study the peptide self-aggregation process (“amyloid formation”, structures and kinetics) using biophysical methods such as NMR, fluorescence or CD spectroscopy. The interactions of Ab with small molecules, or metal ions such as Zn(II) or Cu(II), that modulate the aggregation process can be studied in semi-stationary states by these methods (1). Kinetic effects on the amyloid formation process can be followed by fluorescence, after labeling the material rich in β-structure by the amyloid-specific dye Thioflavin T. The β-hairpin structure of the peptide with a mainly unstructured N-terminus appears to be a basic unit for formation of the larger amyloid structures associated with insoluble fibrils. Smaller oligomeric peptide aggregates, possibly the major cell toxic agents, can be studied by Soft Ionization Mass Spectrometry. Fluorescence Correlation Spectroscopy (FCS) shows the heterogeneity of the aggregation process of ThT-labeled Aβ in terms of time dependent amyloid aggregate sizes, on a single particle level (2). Modulation of the amyloid formation by Zn(II) or Cu(II) ions binding to specific residues in the N-terminus of the Aβ peptide can be followed by FCS, showing changes in structures as well as kinetics for the aggregation process. Understanding the basic properties, molecular interactions and reactions of the major participants in the chemical processes leading to AD gives a firm basis for the future development of agents that may be used in therapies against AD (3,4).

Title: “Assembling responsive nanoparticles”

Time18:00
Place: Hall C, Chemical Center, Naturvetarvägen 14

Abstract

Self-assembly is not only the key construction principle that nature uses so successfully to fabricate its complex molecular machinery, it has also fascinated colloid and materials scientists for decades. Traditional self-assembled materials based on colloidal building blocks suffer from the fact that the emerging structures are often polydisperse and irregular. This has led to a number of exciting developments in order to overcome these deficiencies, such as the construction of more complex colloidal building blocks that allow for the incorporation of directional interactions, a transfer of concepts such as specificity and molecular recognition from supramolecular chemistry to the colloid world, and the use of directed self-assembly. In this seminar I will describe the use of responsive nanoparticles such as thermo- or pH-sensitive microgels as ideal building blocks to investigate the relationship between interactions and self-assembled structures. These particles are not only attractive model systems for basic research, but also of considerable technological importance to materials science and nanotechnology for the fabrication of nanostructured responsive or smart organic-inorganic hybrid materials. The combination of nanoscale inorganic moieties with organic polymers allows us to create materials with enhanced or even completely new properties, and I will show that we can design, synthesize and assemble functionalized responsive nanoparticles in order to make adaptive polymer-colloid nanomaterials with tailored optical, magnetic and mechanical properties.

Title:  "Reflections on the biointerface: Structure, interactions and processes"

Day: Thursday October 19th
Time: 18:00
Place: Hall C, Chemical Center, Naturvetarvägen 14

Abstract

Biological membranes do not only occur as planar bilayer structures, but bilayers have also been shown to, depending on the lipid composition, curve into intriguing 3D structures. In fact the important role of curvature of lipid membranes have been increasingly been recognized. Understanding biological implications of such curved lipid interfaces as well as exploiting their full potential in applications, for e.g. drug delivery and other biomedical applications, poses a challenge that requires the development of novel, well-defined and versatile model system. We will discuss how this can be achieved by the supporting surface topology, e.g. vertical nano-wire arrays, or by changing the lipid composition or by introducing components, e.g. responsive particles, which can alter the curvature as a response to the environment. We will discuss how the lipid self-assembly structure can be change in desired way by adding a particular type of lipolytic enzymes. Here the (oil) triglyceride aqueous interface is important also for other processes like emulsification. Our results show that uptake of water in the triolein phase can occur and this can be affected by the presence of lipolytic enzymes.

Title:  "Asymmetric Autocatalysis and the Origin of Homochirality"

Day: Monday October 30th
Time: 18:00
Place: Hall C, Chemical Center, Naturvetarvägen 14

Abstract

Asymmetric autocatalysis is a reaction in which chiral product acts as a chiral catalyst for its own formation. We found asymmetric autocatalysis of pyrimidyl alkanol with significant amplification of ee in the enantioselective addition of diisopropylzinc to pyrimidine-5-carbaldehyde. Starting from pyrimidyl alkanol with extremely low ee as asymmetric autocatalyst, pyrimidyl alkanol with >99.5% ee was formed. By using asymmetric autocatalysis, the origin of homochirality has been examined. It was found that chiral inorganic crystals such as quartz, chiral isotopomers, chiral crystals composed of achiral organic compounds, circularly polarized light (CPL), enantiotopic face of achiral mineral, i.e., gypsum, act as chiral triggers in asymmetric autocatalysis to afford the product with high ee of the corresponding absolute configuration with those of chiral triggers. Absolute asymmetric synthesis without the intervention of any chiral factor has also been realized by asymmetric autocatalysis.

Title:  "How perturbing the early life microbiome with antibiotics leads to long-term consequences"

Day: Monday May 8th
Time: 18:00
Place: Hall C, Kemicentrum

Abstract

A central feature of mammalian development across an evolutionary timeframe is the high fidelity intergenerational transfer of resident microbes. Yet the developing microbiome, crucial in the early life time-window, has limited resilience. We show that early life antibiotic exposures can alter microbiota development with both metabolic and immunological consequences. This work highlights the importance of early events in shaping the microbiome of developing animals, with effects that may be relevant beyond the current generation.

Title:  "Physical chemistry of skin - Relating molecular characteristics to macroscopic material properties"

Day: Thursday April 20th
Time: 18:00
Place: Hall C, Kemicentrum

Abstract

The outer layer of human skin, stratum corneum, makes up a large interfacial barrier film that protects the body from desiccation and uptake of hazardous chemicals. The healthy skin has low very permeability to most molecules. It is also soft and pliable and it tolerates deformation. Taken together, the stratum corneum fulfills a number of essentially different requirements, and its special material properties can be related to the organization and dynamics in its molecular components, which are mainly lipids and keratin proteins.

In this talk I will discuss how stratum corneum can respond on a molecular level to changes in its environment and when it is exposed to solvents or other small molecules. The molecular effects will then be related to changes in the macroscopic properties of barrier function and swelling.

Title:  "Iron-carbene complexes - towards a revolution in solar energy technology?"

Day: Thursday March 23rd
Time: 18:00
Place: Hall C, Kemicentrum

Abstract

Photosensitizers are used to obtain excited state electrons by harvesting sunlight and then transfer the excited electron to a semiconductor, substrate or another catalyst to drive solar cells and photocatalysis. Photosensitizers to date have to a large extent been based on metal complexes and in particular such ones based on rare and expensive metals, and in particular ruthenium. We have recently shown that metal complexes based on iron, an earth-abundant and inexpensive metal, can be used as  photosensitizers. This research has also led to the first photoluminescent iron complexes.
