Unraveling the Mysteries: how the Coronavirus Interacts with Human Skin

By Archyde Staff | october 27, 2023

Curiosity surrounding the novel coronavirus‘s interaction with human skin is a significant point of interest in understanding it’s transmission. Marc, a researcher, has been delving into this complex relationship through detailed simulation work. This exploration aims to shed light on how the virus might engage with our outermost protective layer.

The primary pathway for coronavirus transmission remains inhalation of respiratory droplets. however, the surfaces we touch, including our skin, can become contaminated. understanding how the virus behaves on skin is key to effective prevention.

Synergies Driving Innovation in Lasting Materials

The Instituto de Ciencia de Materiales de Barcelona (ICMB) – a research institute of the Spanish National Research Council (CSIC) – and the Institute of Chemical Materials and Biotechnology (ICMBA) are forging a powerful collaboration to accelerate research and development in bio-based materials. this partnership focuses on creating sustainable alternatives to customary, petroleum-derived materials, addressing growing environmental concerns and the demand for a circular economy. The core of this collaboration lies in combining ICMB’s expertise in materials characterization and advanced manufacturing with ICMBA’s strengths in biotechnology and the production of bio-based building blocks.

Key Research Areas & Technological advancements

The joint efforts are concentrated on several key areas within sustainable materials science:

Biopolymers: Developing novel biopolymers with enhanced properties – think improved strength, versatility, and thermal stability – derived from renewable resources like starch, cellulose, and proteins. Research includes modifying these polymers to broaden their applications.

Bio-composites: Creating high-performance composite materials by combining biopolymers with natural fibers (flax, hemp, wood flour) or other bio-based fillers. This aims to reduce reliance on synthetic reinforcements.

Lignocellulosic Materials: Utilizing lignin, a complex polymer found in plant cell walls, as a feedstock for producing valuable chemicals and materials. This addresses a notable waste stream from the pulp and paper industry.

Bio-based Additives: Investigating and synthesizing bio-based additives – plasticizers, stabilizers, and flame retardants – to improve the performance and sustainability of existing materials.

Advanced Characterization Techniques: Employing cutting-edge techniques like atomic force microscopy (AFM), X-ray diffraction (XRD), and spectroscopy to understand the structure-property relationships of bio-based materials at the nanoscale. This is crucial for optimizing material performance.

Benefits of Bio-Based Materials: A Sustainable Future

The shift towards bio-based polymers and materials offers a multitude of benefits:

Reduced carbon Footprint: Bio-based materials typically have a lower carbon footprint compared to their fossil-fuel counterparts,contributing to climate change mitigation.

Renewable Resources: Utilizing renewable resources reduces dependence on finite fossil fuels.

Biodegradability & Compostability: Many bio-based materials are biodegradable or compostable, minimizing plastic waste accumulation. Though, it’s vital to note that “biodegradable” doesn’t always mean rapid decomposition in all environments.

Reduced Toxicity: Bio-based materials often exhibit lower toxicity compared to conventional materials, improving human and environmental health.

New Economic Opportunities: The bio-based materials sector is creating new jobs and economic opportunities in agriculture, biotechnology, and manufacturing.

Case Study: Bio-Based Packaging Solutions

A recent project stemming from the ICMBA-CSIC collaboration focused on developing a fully biodegradable packaging material for food products. Utilizing polylactic acid (PLA) derived from corn starch and reinforced with cellulose nanocrystals, the team created a packaging film with comparable barrier properties to conventional plastic films. This material demonstrated complete compostability within industrial composting facilities, offering a viable option to single-use plastics. The project highlighted the importance of bioplastic packaging in reducing environmental impact.

challenges and Future Directions in Biopolymer Research

Despite the significant progress, several challenges remain in the field of biomaterials:

Cost Competitiveness: Bio-based materials often face cost challenges compared to established petroleum-based materials. Scaling up production and optimizing processes are crucial for reducing costs.

Performance Limitations: Some bio-based materials may exhibit limitations in terms of mechanical strength, thermal stability, or barrier properties. Ongoing research is focused on overcoming these limitations through material modification and blending.

Land Use Concerns: The cultivation of biomass for bio-based materials must be done sustainably to avoid competition with food production and deforestation.

End-of-Life Management: Effective infrastructure for collecting, sorting, and composting bio-based materials is essential for realizing their full environmental benefits.

Future research will likely focus on:

Genetic Engineering of Microorganisms: Enhancing the efficiency of microbial production of bio-based building blocks.

Developing Novel Bio-Based Monomers: Exploring new renewable feedstocks and developing innovative monomers for polymer synthesis.

Advanced Polymer Architectures: Designing polymers with tailored properties through precise control of molecular structure and architecture.

Life Cycle Assessment (LCA): Conducting complete LCAs to evaluate the environmental impact of bio-based materials throughout their entire life cycle.
