Anti-Counterfeiting Inks Based on Förster Resonance Energy Transfer in Microcrystalline Cellulose-Grafted Poly(amidoamine) for Artificial Industries

Abstract: Counterfeiting and inverse engineering of different artificial industries have significantly increased, which is a challenge for the originality of the crafts that are known as the cultural products of different nations. To prevent counterfeiting in the art market, it is needed to mark the original crafts with anti-counterfeiting inks using high technologies for their easy authentication. In this study, poly(amidoamine) (PAMAM) dendrimer-modified microcrystalline cellulose decorated with coumarin moieties was … Show more

“…The prepared stable luminescent ink containing fluorescent silica nanoparticles was successfully screen-printed and cured on rigid and flexible substrates. A fluorescent chemosensor-based ink having fluorescein was also reported by Mardani et al The biobased and user-friendly ink presented anticounterfeiting properties applied for the authentication of original artificial industries.…”

“…Fluorescein is a synthetic organic photoactive dye that is widely used as a fluorescent tracer for many applications. , It was first developed in the 1800s and is now recognized as a low-toxic molecule with a high quantum yield that emits long wavelengths when excited at around 500 nm in aqueous media. , Therefore, it is highly suitable for use in high-security anticounterfeiting applications . In this study, latex nanoparticles with different comonomers were synthesized by emulsifier-free emulsion copolymerization approach, then they were doped with fluorescein for 24 h and used in the development of anticounterfeiting inks with applications in tagging security marks, such as barcodes, logos, and identification labeling of money. Here, latex samples were used for the introduction of fluorescein into the different polar matrices.…”

“…FRET is an energy transfer process between a pair of donor and acceptor fluorophores which are linked together via a non-conjugated linker. [101][102][103][104] In this process, a fluorophore donor absorbs and excites the energy from the incident light and then transmits this energy to the acceptor. Several requirements are satisfied in occurrence RET.…”

“…In order to prevent from environmental degradation of the chromic compounds and improve their chromic properties, great efforts have been devoted to prepare chromic polymers. , This type of smart polymers is generally prepared by different methods, where embedding of thermochromic dyes in a polymer matrix is one of the most significant methods . This technique is accomplished by two chemical or physical incorporation methods. Physical incorporation has frequently been used because of the ease of the preparation method and also high preservation of the thermochromic properties of the dye. The polymeric matrix not only plays the carrier role for the thermochromic compounds and increases their lifetime but also has great effects on thermochromic properties, such as color purity and absorption intensity, due to the different polarity of the matrix originating from its different functional groups. , In addition, incorporation of thermochromic dyes into a polymer carrier reduces their consumption, which is highly important in different applications, such as temperature sensors and anticounterfeiting inks . Therefore, the correct selection of the polymer matrix is one of the necessary parameters in the application of thermochromic dyes .…”
