Enhancing the sensitivity of portable biosensors based on self-powered ion concentration polarization and electrical kinetic trapping

Advances in self-powered chemical sensingviaa triboelectric nanogenerator

“…There are many other TENG-powered chemical sensors listed in Table 2 along with those discussed above. 121,[130][131][132][133][134][135] The table shows their design, target molecules, and performances of powering and sensing. Generally, TENG-powered chemical sensors have satisfactory performances: As for the output, a rectifier is often connected to the TENGs to maintain a stable, constant direct current and voltage input to sensors, as a method to meet the requirement of stable power supply for TENGs.…”

Table 2 shows that the TENG has large output voltage or View Article Online current in many cases.…”

A Co-Printed Nanoslit Surface Plasmon Resonance Structure in Microfluidic Device for LMP-1 Detection

“…Biosensing applications were presented to quantify DNA/RNA/micro (mi)RNA [ 35 , 36 , 37 , 38 ], proteins [ 39 ], autoantibodies [ 40 ], cells [ 41 ], and NPs in living cells [ 42 ]. To reduce interference from environmental elements, the integration of biosensors into the microfluidic channel is a good strategy to isolate sensing environments [ 43 , 44 , 45 ]. Other advantages associated with using microfluidics are that these systems use less sample material, are easy to integrate with microfluidics, and can utilize multiplex detection.…”

Detection of Candida albicans Using a Manufactured Electrochemical Sensor

“…Therefore, we see that that most work is being focused on techniques and methods that can rapidly and easily detect candida non-invasively, and that can offer a high sensitivity and accuracy to match the current gold standard in the field, which is culturing cells taken from blood samples. Other novel biosensing techniques, e.g., Brownian nanobeads [ 31 , 32 , 33 , 34 , 35 ], surface plasmon resonance [ 36 ], liquid crystal [ 37 , 38 ], nano-gold clusters [ 39 ], and flow cytometers [ 40 , 41 , 42 ], can also be the potential techniques for Candida detection.…”
