As the human population grows, the anthropogenic impacts from various agricultural and industrial processes produce unwanted contaminants in the environment. The accurate, sensitive and rapid detection of such contaminants is vital for human health and safety. Surface-enhanced Raman spectroscopy (SERS) is a valuable analytical tool with wide applications in environmental contaminant monitoring. The aim of this review is to summarize recent advancements within SERS research as it applies to environmental detection, with a focus on research published or accessible from January 2021 through December 2021 including early-access publications. Our goal is to provide a wide breadth of information that can be used to provide background knowledge of the field, as well as inform and encourage further development of SERS techniques in protecting environmental quality and safety. Specifically, we highlight the characteristics of effective SERS nanosubstrates, and explore methods for the SERS detection of inorganic, organic, and biological contaminants including heavy metals, pharmaceuticals, plastic particles, synthetic dyes, pesticides, viruses, bacteria and mycotoxins. We also discuss the current limitations of SERS technologies in environmental detection and propose several avenues for future investigation. We encourage researchers to fill in the identified gaps so that SERS can be implemented in a real-world environment more effectively and efficiently, ultimately providing reliable and timely data to help and make science-based strategies and policies to protect environmental safety and public health.

“…This system involves the placement of a filter at the tap outlet while using the pressure of the water that comes out of the pipe. [38][39][40] Apart from CNFs and CNCs, their altered derivatives have also been studied abundantly for adsorption of impurities such as heavy metals, dyes, and organic compounds from the water via electrostatic interactions. [41][42][43][44] CNF was found to be an ideal material for membranes, for removing charged pollutants from the aqueous environment through electrostatic interactions along with size exclusion due to its hydrophilicity, tailorable surface geometry, and network formation properties.…”

The demand for purified water has been increasing day by day. More feasible technologies, including membrane filtration, adsorbents, and so forth have emerged out to be more efficient and cheaper over conventional industrial methods. Nanocellulose, being biodegradable, nontoxic, and sustainable nanofiller exhibits excellent mechanical properties, high aspect ratio, high surface area, and more importantly tunable surface chemistry; is a potential candidate to be employed for water purification. Composite membranes and films for water filtration, constituting of biopolymers have gathered immense interest lately. Compared with its unmodified form, the functionalized NC enhances the compatibility with the matrix and readily forming strong network structures; essential for the formation of channels for better adsorption of impurities and higher water flux. This review highlights some of the recent studies dedicated to making and testing of nanofiltration membranes prepared using nanocellulose and its different functionalized derivatives.

“…We then prepared electro-spun nanofibers of agave cellulose and polycaprolactone to produce membranes for water filtration.On the other hand, domestic water filtration systems are widely used throughout the world, since they are very effective. These household filter systems consist of placing a filter at the tap outlet and using the water pressure that comes out of the pipe [26][27][28]. These filters are made of a variety of different materials, such as ceramics, activated carbon, and synthetic polymers [26].…”

Nanocellulose and Polycaprolactone Nanospun Composite Membranes and Their Potential for the Removal of Pollutants from Water

A composite membrane based on polycaprolactone (PCL) and cellulose nanofibers (CNF) with different compositions was prepared using the electro-spinning method, with the objective of developing organic membranes with good mechanical properties to remove contaminants from water. Water is a resource of primary importance for life and human activities. In this sense, cellulose obtained from agave bagasse and polycaprolactone nanofibers was used to prepare membranes that were tested by filtering tap water. The membranes obtained presented a porosity and structure on a nanometric scale. The water quality variables evaluated after filtration with the PCL/CNF membranes showed 100% turbidity removal, 100% conductivity, and heavy metal removal of the order of 75% to 99% for iron and chromium. CNF comprises biowaste derived from tequila production, and it has added value. Electro-spun CNF and PCL membranes can be applied as a "green" and eco-friendly filtration system for water purification.Molecules 2020, 25, 683 2 of 13 about 40% (wet basis) of over 1000 tons of agave grown in Mexico [11]. The availability of such large quantities of agave bagasse [9] poses serious disposal problems, since most of the biomass ends up in clandestine dumps (due to little environmental regulation), causing adverse effects on the fertility of farmland [12], contamination by leachates, and phytosanitary risks due to the inadequate incorporation of this material into the soil [13]. Chemically, agave bagasse is 44.5% cellulose, 25.3% hemicellulose, and 20.1% lignin [7]. Taking advantage of these constituents, there have been many efforts to use agave bagasse for various applications, e.g., the production of biopolymers [14,15], composting [16], animal nutrition [17], generation of biofuels [10,18], reinforcement materials [19], etc. More recently, agave bagasse is being explored for the production of cellulose nanofibers and nanocrystals [7,8,20,21] to further diversify the utilization of this biowaste. On the other hand, electro-spinning of biopolymers has become popular in the manufacture of nanofibers for a variety of added value applications, such as tissue engineering, drug release, sensors, and air and liquid filtration systems [22][23][24][25][26].Our main interest in electro-spinning agave cellulose nanofibers was to produce membranes that can retain suspended particles in water (due to the diameter of the fibers), a membrane with high porosity and good surface area properties. However, the main challenge with the preparation of electro-spun agave cellulose was the poor solubility of cellulose that was to be dispersed into an electro-spinnable liquid [24]. We overcame the poor solubility challenge by dissolving agave cellulose in dimethylformamide (DMF) and blending with polycaprolactone to prepare a composite electro-spun blend, subsequently producing electro-spun nanocellulose and polycaprolactone membranes. The main objective of using a copolymer blend was to improve technical properties, such as contaminant retention capacity, therma...
