Rapid Prototyping of Thermoset Polyester Microfluidic Devices

Abstract: This paper presents a simple procedure for the fabrication of thermoset polyester (TPE) microfluidic systems and discusses the properties of the final devices. TPE chips are fabricated in less than 3 h by casting TPE resin directly on a lithographically patterned (SU-8) silicon master. Thorough curing of the devices is obtained through the combined use of ultraviolet light and heat, as both an ultraviolet and a thermal initiator are employed in the resin mixture. Features on the order of micrometers and greate… Show more

“…O Streptococcus mutans é considerado o principal iniciador do processo carioso 16 sendo, particularmente, sensível à ação da clorexidina, antimicrobiano mais utilizado no ambiente odontológico 20,21 , o que foi confirmado neste trabalho. Como alguns trabalhos relatam que, com grande frequência, a clorexidina pode causar alguns efeitos adversos, vêm-se estudando os produtos naturais.…”

“…Amostras de Streptococcus mutans (SM) (ATCC 25175) foram ativadas em meio BHI e incubadas a 37 °C por 24 horas [14][15][16] . Foram inoculados 50 µL de SM em solução salina estéril (NaCl 0,85%) até que fosse obtida uma turvação compatível com o grau 0,5 da escala Mac Farland (1x10 6 UFC/ mL).…”

“…The introduction of thermoset polyester (TPE) as an alternative microchip material has shown promise as a merger between the ease of fabrication and cost effectiveness of PDMS, with the higher separation efficiencies and increased stability of PMMA and PC [41]. The process of fabricating TPE as a microfluidic device has been described previously by Fiorini et al [41,42].…”

“…The process of fabricating TPE as a microfluidic device has been described previously by Fiorini et al [41,42]. With fabrication techniques similar to PDMS, little to no modification to existing soft lithography techniques are needed [43,44].…”

“…Soft lithography allows rapid fabrication of complex microfluidic structures 12 in flexible polymer substrates at a fraction of the cost of traditional glass or semiconductor manufacturing. Although the most popular polymer is poly(dimethylsiloxane) (PDMS), many other materials are suitable, such as photocurable hydrogels 13 , thermoset plastics 14 and elastomers 15 , and photocurable solvent-resistant elastomers such as perfluoropolyethers (PFPE) 16 . The optical transparency and good optical quality of PDMS has been demonstrated in applications such as soft lithographic fabrication of blazed gratings 17 and solid immersion lenses 18 , showing that these materials are suitable in the optofluidic context.…”
