Recent advances and future trends on molecularly imprinted polymer-based fluorescence sensors with luminescent carbon dots

Green Aspects in Molecularly Imprinted Polymers by Biomass Waste Utilization

“…Thus, with the aim to enhance selectivity, sensitivity, and anti-interference ability, some attempts to apply CDs in the MIP field have been made in the last few years. Note that the relevance and success of the carbon dot-based MIP research area has been demonstrated from the publication of some reviews in 2020 with this specific topic where a description in deep several studies of CDs combined with MIP can be found [ 20 , 103 , 104 ], where optical/ fluorescence sensors represent the main explored application of CDs combined with MIP. In this context, even if Ansari et al [ 20 ] dedicated a paragraph for CDs derived from biomass waste, they reported only two examples where CDs were synthesized from sweet potato peels and cedrus, respectively [ 105 , 106 ].…”

Thus, herein other relevant studies recently appeared in literature will be described highlighting some aspects of carbon dots synthesis from biomass waste.…”

“…In addition, their production is less expensive with a very high storage life, keeping their recognition capacity also for several years at room temperature [ 15 , 16 , 17 , 18 ]. MIPs’ advantageous features permitted an extensive application in analytical field such as foods, drugs, biological, and environmental sectors for the detection, preconcentration or separation of several analytes [ 19 , 20 , 21 , 22 ]. Other MIPs applications such as drug delivery [ 23 ] and catalysis [ 24 , 25 , 26 ], tissue engineering [ 27 ] have be also considered.…”

“…In the last decade, several high-quality reviews have been written on molecular imprinting [ 15 , 16 , 17 , 18 ], but most of them have dealt with the fundamental aspects and characteristic applications of MIPs while few review articles on novel techniques related to their preparation. Recently, only a few reviews highlighting the green aspect in MIPs preparation have been published [ 20 , 28 , 29 , 30 , 31 ]. On the other hand, to the best of our knowledge, there are no reviews focused on the transformation of biomass waste to produce natural substrates that can be used in place of other toxic substances generally employed for MIPs design.…”

Molecularly Imprinted Polymer-Based Sensors for Priority Pollutants

“…Recently, review manuscripts have been published, describing imprinted polymers in combination with sensor devices that work based on a specific detection technique like electrochemical [102,103] or optical methods [104,105]. This review aims to provide an overview of the developed strategies for modification of sensor devices, that work based on different detection techniques (including optical, electrochemical, electromechanical and chemiresistive sensors), with MIPs (MIP particles or MIP thin layers were used either directly or in a nanocomposite) for a broad range of important chemicals with different physical-chemical properties.…”
