“…In recent times many research groups have used ESM to prepare AgNPs, AuNPs and other oxide materials. 12,13,[17][18][19] The metal NP immobilized ESM has shown unique advantages in biosensing, 20 surfaceenhanced Raman spectroscopy 21 and in catalysis. 22,23 The ESM can also act as a platform to retrieve heavy toxic metal ions, such as arsenic and mercury, from water.…”

Chicken egg shell membrane, a naturally abundant protein membrane, was used to synthesize gold (Au), silver (Ag) and their bimetallic (AuAg) alloy nanoclusters at room temperature without the use of any reducing agent or catalyst. The as-formed gold and alloy clusters were highly fluorescent and exhibited intense blue emission around 435 AE 5 and 440 AE 5 nm, respectively. This is the first report confirming the formation of fluorescent alloy clusters exhibiting nanosecond lifetimes by a biomembrane-induced reduction process. We have also explored the capability of these metal cluster immobilized inexpensive ESMs in removing organic dyes from water. The results confirmed that it is the strong adsorption of the dye molecules in the presence of the metal particles that has helped to convert ESM into an effective platform for water purification. This process has the dual advantages of utilizing an inexpensive, abundant and eco-friendly food waste (egg shell membrane) for in situ reduction and formation of metal nanoparticles and the utilization of the same as an effective platform for the removal of anionic dyes from waste water. An Au-immobilized ESM showed a better efficiency in dye molecules removal than those of the Ag-ESM and AuAg-ESM membranes.

“…Recently, researchers have been inspired by naturally occurring submicron structures to develop facile, low-cost, and green SERS substrates for various applications [ 11 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. Numerous insects, birds, and plant leaves exhibit a wide array of complex periodic and quasi-periodic micro/nanostructures, which have been exploited by coating a gold or silver thin film.…”

“…Hence, eggshell is an important bio-template for SERS applications. As an example, Lin et al deposited Ag nanoparticles (180–210 nm) on 3D porous chicken eggshell membrane and reported the SERS enhancement factor of ~10 4 to ~10 7 [ 24 ]. However, very few studies have been reported regarding eggshell membrane as natural SERS substrate.…”

A simple technique is presented to fabricate stable and reproducible plasmonic substrates using chicken eggshell as bio-templates, an otherwise everyday waste material. The 3-dimensional (3D) submicron features on the outer shell (OS), inner shell (IS), and shell membrane (SM) regions are sputter coated with gold and characterized for surface-enhanced Raman scattering (SERS) performance with respect to coating thickness, enhancement factor (EF), hot-spots distribution, and reproducibility. The OS and IS substrates have similar EF (2.6 × 106 and 1.8 × 106, respectively), while the SM provides smaller EF (1.5 × 105) due to its larger characteristic feature size. The variability from them (calculated as relative standard deviation, %RSD) are less than 7, 15, and 9 for the OS, IS, and SM substrates, respectively. Due to the larger EF and better signal reproducibility, the OS region is used for label-free sensing and identification of Escherichia coli and Bacillus subtilis bacteria as an example of the potential SERS applications. It is demonstrated that the detection limit could reach the level of single bacterial cells. The OS and IS regions are also used as templates to fabricate 3D flexible SERS substrates using polydimethylsiloxane and characterized. The simple, low-cost, and green route of fabricating plasmonic substrates represents an innovative alternative approach without the needs for nanofabrication facilities. Coupled with hyperspectral Raman imaging, high-throughput bio-sensing can be carried out at the single pathogen level.

“…[ 25,116–118 ] Besides, the eggshell membrane is also used to fabricated flexible SERS substrates. [ 119–121 ] As a natural biomaterial, eggshell membrane consists of large numbers of amino groups, carboxyl groups, and partial sulfhydryl groups. Some metal ions or nanoparticles can be captured on the surface of eggshells through chemical or physical interaction with the functional groups.…”

Flexible surface‐enhanced Raman scattering (SERS) substrates have recently attracted growing research interests in real‐world applications due to their unique advantage of sensitivity and flexibility. Reviewing the latest progress of flexible SERS substrates is very important for further development of high‐quality detection platforms. Herein, the recent developments of flexible SERS substrates in fabrications and applications are introduced. First, three categories of current flexible SERS platforms including paper‐based SERS substrates, polymer‐based SERS substrates, and inorganic materials‐based SERS substrates are demonstrated in depth. Then, the focus is moved to the applications of flexible SERS substrates. Combining swab strategies, lateral flow strips, paper‐based microfluidics, and in situ detection techniques, flexible SERS platforms provide intriguing applications in various fields. The challenges are also identified for practical applications on account of substrates’ uniformity, quantitative accuracy, multiplex detection ability, and overall cost. It is believed this review will be of help for researchers to design and fabricate flexible SERS substrates with higher performance and lower cost, and finally realize the practical applications.
